- Description: Subtropical thicket supports a large variety of indigenous browsing herbivores, such as elephants, black rhino, kudu and bushbuck, but impala historically never occurred in the Eastern Cape. The aim of this study was to determine what impacts extralimital impala (Aepyceros melampus) have on subtropical thicket. The thicket of the Shamwari Game Reserve, Eastern Cape, was used for the study. To quantify the effects of impala, feeding behaviour and diet was investigated during summer and winter. Sixteen impala were also enclosed in a camp of subtropical thicket where they would be limited to feedings on thicket. Vegetation composition and structure were monitored for a period of 12 months in the enclosure. Impala followed the expected high percentage graze and a low percentage browse in thicket in summer. However, the expected was not observed during winter: at this time grazing and browsing were equally important. Field collection of feeding behaviour data showed that impala are attracted to fringes of intact bush clumps or degraded thicket. Analysis of the impala diet confirmed this, with a significantly higher percentage graze (48 percent) than browse (22 percent) during summer. However, during winter, diet analysis indicated grazing to be much higher (36 percent) than browsing (6 percent) with the impala temporarily taking advantage of nutritious grasses still present. The enclosed portion of thicket was originally at 80 percent ecological status but it showed significant changes after addition of 16 impala. Animal trails increased in number and in width, resulting in a trampling effect. Grass cover was significantly different inside the enclosure after 12 months compared to outside. The amount of available browse of the enclosed thicket was also significantly different after addition of the impala. It is concluded that impala have a negative effect on thicket, with trampling the most significant effect. Long term monitoring of the effects of extralimital impala in different types of thicket will be required to accurately quantify their direct effects on subtropical thicket in the Eastern Cape. The main aim of this study was to determine the impacts of impala on Thicket. The study showed significant impacts on Thicket as found in Shamwari, and therefore the aim of the study was achieved.

- 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.

- Description: South African producers are constantly facing competition from foreign organisations in their domestic markets. The adverse effects of this competition stem, in part, from the low levels of productivity which characterise South African industry and which is well documented by the National Productivity Institute of South Africa. The concept of continuous improvement offers a proven methodology for increasing the effectiveness and efficiency of production processes. Given the situation that faces South African producers, it would seem appropriate to investigate how the concept of continuous improvement can be applied to a specific South African manufacturing organisation, like the Aspen Pharmacare General Facility, in order to improve its effectiveness and efficiency.

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

- Description: This research project has its origin and motivation in work done by Lysaker, Johannesen and Lysaker (2005), which explored the experience of being as a person with schizophrenia in relation to other individuals. 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.

- 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.

- 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: 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.

- 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.

- Description: A novel glucose oxidase from Penicillium canescens (Tt42) was isolated, purified and characterised. The P. canescens Tt42 was cultivated using an optimised growth medium from literature, and maximum glucose oxidase activities of 11.5 U/ml and 6.9 U/ml for the intra- and extracellular fractions were obtained. Maximum glucose oxidase production was achieved after 72 hours at 28°C which coincided with glucose depletion. A total of 1104 U (from 60ml) of glucose oxidase was produced with a biomass specific glucose oxidase activity of 1.08 Umg[superscript -1] Four methods of cell disruption were evaluated for release of intracellular glucose oxidase from P. canescens Tt42 cells. These methods were; sonication, French press, Freeze-Thaw and a high pressure cell disrupter (Z-Plus Series) from Constant systems. All the methods were successful in releasing the intracellular glucose oxidase from P. canescens Tt42. The use of the Constant Systems high pressure cell disrupter was preferred, since it was the simplest and most rapid method. Ammonium sulphate precipitation was shown to be effective as an initial purification step for extracellular glucose oxidase from P. canescens Tt42. Comparison of the intra- and extracellular glucose oxidase fractions using isoelectric focusing showed 2 isoenzymes in both fractions. The pI values of the isoenzymes were determined to be 4.30 and 4.67, with the former being dominant. Since both the intra- and extracellular fractions contained the same isoenzymes of glucose oxidase, further purification studies were performed using the extracellular fraction. The glucose oxidase from P. canescens Tt42 was purified using 3 main techniques: ammonium sulphate precipitation (60% - 70% cut), anion exchange chromatography (Super Q 650M) and size exclusion chromatography (Sephadex S200HR). The glucose oxidase was determined to be ±80% pure by size exclusion chromatography. The final purified glucose oxidase was lyophilised, and an overall purification yield of 10.3% was achieved with an 8.6-fold purification. The purified glucose oxidase was confirmed to be catalase free. Glucose oxidase from P. canescens Tt42 was determined to be a dimeric protein (M[subscript r] ±148kDa) likely consisting of 2 equal subunits (M[subscript r] ± 70kDa). The temperature optimum range was shown to be 25-30°C. The optimum pH for the oxidation of β-D-glucose was pH 7. The enzyme was shown to be stable at 25°C for 10 hours, with a half life of approximately 30 minutes at 37°C. The lyophilised enzyme was stable at -20°C for 6 months. The properties of glucose oxidase from Tt42 were comparable to alternative glucose oxidase enzymes from Aspergillus and other Penicillium species. Glucose oxidase from P. canescens Tt42 was shown to have distinct kinetic characteristics. The V[subscript max] and K[subscript m] were shown to be 651 Umg[superscript -1] and 18.4 mM towards β-D-glucose. The catalytic kcat and specificity k[subscript cat]/K[subscript m] constants for glucose oxidase from P. canescens Tt42 were shown to be 791 s[superscript -1] and 40 s[superscript -1]mM[superscript -1] each respectively. The specificity constant (k[subscript cat]/K[subscript m]) of glucose oxidase from P. canescens Tt42 was determined to be 1.3-fold higher than that that of A. niger (Sigma Type VII) and 8.7-fold lower than that of P. amagasakiense (ATCC 28686) from literature.

Lack of job satisfaction has been identified as one of its causes. The purpose of this study was: To provide an overview of relevant literature concerning job satisfaction. To determine, by means of an empirical survey, whether doctors in the public sector experienced any factors, which were affecting their job satisfaction levels. To make recommendations as to how the job satisfaction levels of doctors in public sector hospitals could be increased. For the empirical study a survey, with a questionnaire as data collecting tool, was conducted among 59 permanently employed doctors at the Dora Nginza Hospital in Port Elizabeth. The questionnaire focused on biographical information, personality-job fit, job content factors and job context factors. For Section B, C and D of the questionnaire, the response options were structured according to a Likert-type scale. Respondents had to indicate the extent to which they agreed with each statement in the questionnaire. The responses obtained from the survey were presented and analysed. The researcher observed in this study that doctors were just satisfied with their jobs. Apart from the personality job fit factor of job satisfaction where excellent scores were recorded, there seemed to be problems with job content and job context factors. Management of Port Elizabeth Hospitals Complex has a challenge in improving job satisfaction of their doctors in these areas. The researcher recommends that management of Port Elizabeth Hospitals Complex should look into the satisfaction level of doctors in their employment. Doctors’ satisfaction level should be improved from being just satisfactory to being excellent.

- Description: Varieties of Lantana camara (lantana) have been introduced into many countries of the world as ornamental plants and have become invasive weeds in many countries including South Africa. In South Africa, it mostly invades the sub-tropical eastern and northern range. Mechanical and chemical control options are expensive and ineffective. A biocontrol programme was initiated in South Africa in 1961. To date, 22 insect species, and a fungus have been introduced, of these 10, and the fungus have established. Three indigenous lepidopteran species and an exotic generalist pest mealybug are also associated with the weed. The variable success of some of the agents released on L. camara worldwide has been ascribed to a few factors. One important aspect is the large range of varieties encountered in the field. It is therefore essential to be able to predict the possible establishment and impact of agents on many varieties. Laboratory trials on five of the established agents showed clear varietal preferences. In the field, most of the biocontrol agents had limited geographic ranges, linked to altitudinal conditions, as higher populations were recorded at low lying warm summer rainfall areas. A pink and orange flower corolla lobe and throat colour combination and plants with few to medium leaf hairs were most abundant in South Africa. Most of the agent species had individual preferences towards different flower colour combinations, as the agents built up different population levels on varieties in the field, within the suitable geographic region for the insect species. Eight agents preferred smooth leaved varieties, while three preferred hairy leaves, and three had no specific preference to leaf hairiness. Varietal preferences thus did play a significant role in agent populations and accompanied impact achieved in the field. New candidate agents need to be proven specific under quarantine conditions and the results extrapolated to predict specificity in the field, while avoiding potential non-target effects. Many authors have questioned the validity of laboratory host specificity trials. The conventional wisdom is that insects portray a far wider host range in the laboratory than what they would do in the field. In other words, laboratory studies measure the physiological host range of an agent and are conservative and usually don’t reflect the ecological host range of agents in the field. To avoid unnecessary rejections of biocontrol agents, this study has made a retrospective study of the host specificity of agents established in the field. Their laboratory and field host ranges were compared and it was found that virtually all the agents reflect similar or less non-target effects in the field than predicted during multiple choice trials. Of the 14 agents, only one introduced species, Teleonemia scrupulosa, and the indigenous species, Hypena laceratalis and Aristea onychote were able to sustain populations on non-target species in the field in the absence of L. camara. Insect populations on non-target species were much reduced compared to that on L. camara. Furthermore non-target effects were only recorded on plant species closely related to the target weed. The multiple choice trials therefore predict field non-target effects accurately. Predictions of non-target effects of candidate agents can therefore be accurately predicted by laboratory studies, in terms of species likely to be affected and to what extent. One field that need further study though is the impact of non-target effects, especially on Lippia species by L. camara biocontrol agents.

- Description: Varieties of Lantana camara (lantana) have been introduced into many countries of the world as ornamental plants and have become invasive weeds in many countries including South Africa. In South Africa, it mostly invades the sub-tropical eastern and northern range. Mechanical and chemical control options are expensive and ineffective. A biocontrol programme was initiated in South Africa in 1961. To date, 22 insect species, and a fungus have been introduced, of these 10, and the fungus have established. Three indigenous lepidopteran species and an exotic generalist pest mealybug are also associated with the weed. The variable success of some of the agents released on L. camara worldwide has been ascribed to a few factors. One important aspect is the large range of varieties encountered in the field. It is therefore essential to be able to predict the possible establishment and impact of agents on many varieties. Laboratory trials on five of the established agents showed clear varietal preferences. In the field, most of the biocontrol agents had limited geographic ranges, linked to altitudinal conditions, as higher populations were recorded at low lying warm summer rainfall areas. A pink and orange flower corolla lobe and throat colour combination and plants with few to medium leaf hairs were most abundant in South Africa. Most of the agent species had individual preferences towards different flower colour combinations, as the agents built up different population levels on varieties in the field, within the suitable geographic region for the insect species. Eight agents preferred smooth leaved varieties, while three preferred hairy leaves, and three had no specific preference to leaf hairiness. Varietal preferences thus did play a significant role in agent populations and accompanied impact achieved in the field. New candidate agents need to be proven specific under quarantine conditions and the results extrapolated to predict specificity in the field, while avoiding potential non-target effects. Many authors have questioned the validity of laboratory host specificity trials. The conventional wisdom is that insects portray a far wider host range in the laboratory than what they would do in the field. In other words, laboratory studies measure the physiological host range of an agent and are conservative and usually don’t reflect the ecological host range of agents in the field. To avoid unnecessary rejections of biocontrol agents, this study has made a retrospective study of the host specificity of agents established in the field. Their laboratory and field host ranges were compared and it was found that virtually all the agents reflect similar or less non-target effects in the field than predicted during multiple choice trials. Of the 14 agents, only one introduced species, Teleonemia scrupulosa, and the indigenous species, Hypena laceratalis and Aristea onychote were able to sustain populations on non-target species in the field in the absence of L. camara. Insect populations on non-target species were much reduced compared to that on L. camara. Furthermore non-target effects were only recorded on plant species closely related to the target weed. The multiple choice trials therefore predict field non-target effects accurately. Predictions of non-target effects of candidate agents can therefore be accurately predicted by laboratory studies, in terms of species likely to be affected and to what extent. One field that need further study though is the impact of non-target effects, especially on Lippia species by L. camara biocontrol agents.

- Description: Effective change leadership is important to any organisation undergoing fundamental transformation. In particular, the ability of senior public sector leaders to successfully drive strategic change is crucial to meeting the developmental and service delivery challenges faced by the Province of the Eastern Cape in ensuring the effective, efficient and innovative government demanded by all its various stakeholders. The creation on 3 October of a Shared Legal Service situated in the Office of the Premier provided a unique opportunity to examine the leadership of this change initiative in the context of the organisational culture that existed in the provincial public service. This thesis consequently probes the phenomenon of effective change leadership by means of an examination of the understandings of the three change agents involved in driving the transformation of the provision of legal advisory services to the provincial administration and its constituent departments. The picture which emerges from the insights of the participants is one that casts a shadow over the validity of the contemporary theory of transformational leadership. Furthermore, the research conducted has identified the need to view the nature of effective change leadership through a more nuanced, situation-specific lens: one that appreciates the role of relationships and emotions, and that recognises the importance of culture and its impact on the success of organisational transformation. The case study of the Shared Legal Service change initiative provides useful insights into the many and varied challenges faced by public sector leaders in driving strategic transformation in the provincial administration. It offers an example of successful change leadership and demonstrates the need for change agents within the public service to harness more emotionally resonant and relational forms of leadership if they are to soar to new heights in meeting the service delivery expectations of all who look to provincial government to deliver the fruits of democracy.

- Description: The study examines the issue of living conditions in informal settlements, using the case study of Imizamo Yethu informal settlement in Cape Town. Affordability, lack of space, job related issues, a relatively small formal housing stock available in many urban centres, and deregulation, in terms of both access to land and finance, forced lower income groups to seek accommodation in informal settlements. Here people are exposed to unhealthy living conditions. The study reveals that living in informal settlements often poses significant health risks. Sanitation, food storage facilities and drinking water quality are often poor, with the result that inhabitants are exposed to a wide range of pathogens and houses may act as breeding grounds for insect vectors. In informal settlements people often live in temporary homes constructed with impermanent, basic materials. These inhabitants frequently have little option but to live on marginal land (flood plains or steep slopes, for example), with the consequence that they are the first to suffer the effects of cyclones and floods. In addition, a combination of overcrowding, the use of open fires and flammable buildings leads to danger from accidental fires, burns and scalding. The post-apartheid South African government has tried a number of housing initiatives to help alleviate the housing problem since 1994 when it came to power. These have included the Botshabelo Accord (1994), the Housing White Paper in 1995, the National Urban and Reconstruction Housing Agency in 1995, the Housing Subsidy Scheme in 1995, the Housing Act No. 107 of 1997 and the Policy on People’s Housing Process (1998). The government set itself a target of delivering one million houses within five years. By all indications the government did not fully comprehend the gravity of the problem in relation to available resources. In 2004, the Department of Housing declared its intention to eradicate informal settlements in South Africa by 2014. This followed the unprecedented housing backlog, proliferation of informal settlements, social exclusion and the inability of municipalities to provide basic infrastructure to urban poor households. However, despite these bold interventions by government, the study demonstrates that the provision of low-cost housing can be viewed as a wicked problem. Wicked problems are described to be “ill-defined, ambiguous, and associated with strong moral, political and professional issues”. The study, therefore, concludes that given the complexities surrounding the provision of low-cost housing in South Africa, the government’s ambitions to resolve housing backlogs by 2014 appear to be a far-fetched dream.

- Description: The purpose of this study is to look at instilling discipline of learners at schools after corporal punishment was abolished by identifying causes of disciplinary problems, alternatives to corporal punishment, and the attitudes of learners, teachers and parents towards alternatives. Data were collected through questionnaires, interviews and observation. Data were collected from learners, teachers and parents. Two neighbouring schools in the Mthatha District of Education were used. A qualitative research approach was used in the study. Findings reveal and support literature consulted that there is a wide range of causes of disciplinary problems at schools. According to the findings, the outstanding difference between respondents on causes of disciplinary problems was on home background. Learners are not in agreement with literature, teachers and parents who all agree that background is the cause of misbehaving of learners at school. The study reveals that learners, teachers and parents hold different views about alternatives to corporal punishment. While teachers, parents and literature are in agreement on using parental involvement as an alternative to caning, learners do not want parents to be involved. Teachers, the findings reveal, are not in favour of alternatives that need to be supervised by them. The final outcome of this study focuses on positive alternatives to corporal punishment. These include parental involvement, manual work, the application of school rules and enforcement of the code of conduct. Learners would also like to be disciplined and parents are in favour of being involved in the maintenance of discipline in schools.

Making sense of Men's Health: an investigation into the meanings men and women make of Men's Health

- Description: This study investigates the popular pleasures produced by readers of men's magazines, focusing primarily on the publication, Men's Health, which represents a new type of magazine catering for men. Using qualitative research methods such as textual analysis and reception analysis, the study explores the pleasures produced by both men and women from the consumption of such texts. The theoretical perspective of cultural studies informs this project, an approach that focuses on the generation and circulation of meanings in society. Focusing on the notion of the active audience and Hall's encoding/decoding model, this study examines readers' interpretations of the Men's Health text, focusing on the moment of consumption in the circuit of culture. Reception theory proposes the existence of "clustered readings" produced by interpretive communities that are socially rather than individually constructed. As a critical ethnography, the study interrogates these meanings with particular reference to questions of gender relations and power in society. Access to different discourses is structured by the social position of readers within relations of power and this study takes gender as a structuring principle. Therefore, this study also explores the particular discursive practices through which masculine and feminine imagery is produced by the Men's Health text and by its readers. The research findings support the more limited notion of the active audience espoused by theorists such as Hall (1980) offering further evidence to suggest that readers produce readings other than those preferred by the text and that therein lies the pleasure of the text for male and female readers. The research concludes that the popularity of Men's Health derives from the capacity of its readers to make multiple meanings of the text.

Manifestations of nihilism in selected contemporary media

- Description: This study focuses on the concept or phenomenon of nihilism, given the regularity with which it manifests itself (to anyone who is aware of it in more or less theoretical or philosophical terms) in all kinds of cultural artifacts such as films, television shows or series, books such as novels or philosophical texts, and magazines. Most of these artifacts can be grouped together under the heading of the media in the present era. The objective of the study is to use the concept of nihilism to identify and analyse selected cases in contemporary media -- in the form of films and television series – to answer the question, with what kinds of nihilism people would come face to face if they knew how to recognize them. The study begins with an outline of a theoretical framework concerning the concept of nihilism. A number of thinkers’ work is used to come to grips with the complex phenomenon, but mostly it is Nietzsche whose thought seems to be valuable for present purposes. In the second chapter the spotlight falls on what is called (in this study) ‘capitalist nihilism’, which seems to belong with what Nietzsche called ‘passive nihilism’, but also seems to exhibit some aspects of ‘active nihilism’. The third chapter is an examination of nihilism in a foreign (Japanese) culture by concentrating on Japanese anime, to test the differences between Western (historically Christian) culture and one with a different cultural and religious history. The last chapter consists of the analysis of a specific (Western) film, I ‘heart’ Huckabees, which was selected because of the variety of ‘nihilisms’ found in it. The study seems to confirm that nihilism is indeed widespread in contemporary, postmodern culture.
