- Description: Interactions between insects have been shown to be important regulators of population abundances and dynamics as well as drivers of spatial segregation and distribution. These are important aspects of the ecology of insects used in biological control and may have implications for the overall success of a particular programme. In the history of biological control there has been a tendency to release a suite of agents against a weed, which in some cases has increased the level of success, while in others little change has been observed. In most of these cases the implications of increasing the level of complexity of the system is not taken into account and there is little research on the effect of releasing another agent into the system. A brief meta-analysis was done on all the biological control programmes initiated in South Africa. Emphasis was placed on multi-species releases and the effects that overlapping niches were having on the number of agents responsible for the success of a programme. Where overlapping niches were present among agents released the number of agents responsible for success was lower than the number established. Water hyacinth, Eichhornia crassipes (Martius) Solms-Laubach in South Africa has more arthropod agents released against it than anywhere else in the world, yet control has been variable. If the biology and host utilisation of all the agents against water hyacinth is considered, a definite overlap of niches is apparent in at least one life stage of all the agents. Therefore the probability of these insects interacting is high, especially if they are established at the same site in the field. Three of the insects released in South Africa have been selected to investigate possible interactions. They are Neochetina eichhorniae Warner, Neochetina bruchi Hustache and Eccritotarsus catarinensis (Carvalho). Y-tube olfactometer bioassays were used to measure responses of these insects to water hyacinth with prior feeding damage by either conspecifics or heterospecifics. This was done to determine whether olfactory cues played a role in host acceptability and avoidance of conspecifics or heterospecifics. The insects were given a choice between damaged and undamaged plants in various combinations. There was a significant preference for the undamaged plants when given a choice between undamaged and damaged plants. However when the insects were given a choice between two damaged plants there was no discrimination between heterospecific or conspecific damaged plants. This may indicate that there is little or no ecological cost for the insect to share a plant with other insects utilising a similar resource. Insect – insect interactions were investigated in a common garden plot experiment to measure the impact that pairwise combinations of the insect may have on their performance. There was a significant interaction between the mirid E. catarinensis and the weevil N. eichhorniae, with the weevil not performing as well when in combination with the mirid than when alone. Interestingly there was a negative interaction between the two weevil species when in combination, however it was impossible to determine which species was being affected if not both. None of the insects performed significantly better when in combination with another insect. A field study on Wriggleswade Dam in the Eastern Cape, South Africa was initiated to determine whether the relationship between the mirid E. catarinensis and the weevil N. eichhorniae could be determined in the field. The performance of the insects at the different sites in the field suggests that there was an interaction between the agents. This interaction did not limit the establishment of either insect at a site, but it did result in one insect dominating at a site over another. Interactions between the three species of insect tested in this thesis suggest that there are both negative and neutral relationships between them. A basic comparison between the insect performances from 15 sites around the country was done to determine if the spatial segregation observed in the field could be extrapolated to the natural South African situation. The interaction observed between N. eichhorniae and E. catarinensis does seem to extrapolate to the general South African situation where there is definite spatial segregation on a landscape level. The co–occurrence of the two Neochetina weevils at these sites suggests that the negative relationship observed between them in the common garden experiment does not extrapolate to the field. The results from this thesis suggest that the interactions between the agents tested would not limit establishment or have significant ramifications on performance. However, there may be spatial and temporal segregation of these species in the introduced range.

- Description: In South Africa conservation is still largely framed in terms of Western scientific values, with a focus on material benefits to local communities, whilst little is known about the intangible values local people attach to nature and biodiversity. We explored the cultural, spiritual and emotional relationships with nature expressed by Xhosa people, within the MaputalandPondoland-Albany Hotspot, as well as the activities that mediate this relationship. A descriptive research approach was applied to document the emotions, meanings and values associated with landscape elements. This approach included group and individual interviews and ‘walk-in-the-woods’ interviews and participatory mapping exercises. Respondents portrayed a strong, although not always easily articulated, appreciation for nature, especially ihlathi lesiXhosa (‘Xhosa forest’, vegetation types within the Thicket Biome).

- Description: Community-Based Natural Resource Management (CBNRM) is considered a win-win approach to reconcile conservation with natural resource use. CBNRM aims to accomplish conservation whilst prioritising development and contributing to poverty alleviation. This study analysed the different components of a CBNRM initiative, Bigodi Wetland Sanctuary (BWS), located in western Uganda. The study was carried out by interviewing the managing committee members (n= 8) as well as local households (n= 68) regarding the manner in which the project works, and the associated benefits and constraints. The main management issues recognised were a lack of monitoring and committee cohesiveness. The information gathered through the household survey enabled the calculation of the value of local livelihood options. This was done on the premise that conservation is better accepted when land users realise the economic value of natural resources. The average annual value of household livelihoods was represented by 30% crop production, 57% natural resource use, and 13% livestock. Lastly, wetland assessments were performed using the WET-Health and WET-EcoServices methodologies from the Wetland Management Series. These assessments indicated that the impacts of local livelihoods on the wetland were currently low but potential issues could arise with the increasing human population density. Ultimately, BWS presents both environmental and social costs and benefits. With a detailed and interdisciplinary method specific recommendations of improvement can be made to reduce such costs and further reconcile the conservation of Bigodi Wetland with local natural resource use..

- Description: Market abuse practices may directly or indirectly give rise to diverse problems such as inaccurate stock market prices, low public investor confidence, reduced market integrity and poor efficiency in the affected financial markets. This thesis reveals that three major forms of market abuse, namely insider trading, prohibited trading practices (trade-based market manipulation) and the making or publication of false, misleading or deceptive statements, promises and forecasts relating to listed securities (disclosure-based market manipulation) are prohibited in South Africa. However, although South Africa has had market abuse legislation for about 30 years, and must be commended for its great effort to enhance market integrity by combating market abuse practices, the enforcement of such legislation is still problematic. Moreover, in spite of the fact that there is no empirical data or accurate figures quantifying the occurrence and extent of market abuse activities in the South African financial markets, this thesis submits that market abuse practices are still to be completely eradicated. Accordingly, this thesis suggests that the aforementioned problem might have been aggravated by inter alia, various gaps, flaws and/or inconsistent implementation and enforcement of the market abuse legislation in South Africa. To this end, the anti-market abuse enforcement framework under the Securities Services Act 36 of 2004 is analysed to investigate its adequacy. The co-operation and role of the Financial Services Board, the courts, the Directorate of Market Abuse and other relevant stakeholders is also examined and discussed. Moreover, the co-operation between the Financial Services Board and similar international agencies is discussed to gauge its effectiveness in relation to the combating of cross-border market abuse practices. The adequacy of the awareness and preventative measures in place to curb market abuse practices is also investigated to determine whether such measures are robust enough to combat other new challenges that were posed by the 2007 to 2009 global financial crisis. Furthermore, a comparative analysis is undertaken of the enforcement of the market abuse prohibition in other jurisdictions, namely the United States of America, the United Kingdom, the European Union and Australia. This was done to investigate the relevant lessons that can be learnt or adopted from these jurisdictions. The thesis further discusses the adequacy of the recently introduced provisions of the Financial Markets Bill as well as the subsequent market abuse provisions of the Financial Markets Bill 2012. The thesis highlights that the aforementioned Bills are positive attempts by the policy makers to improve the enforcement of the market abuse provisions in South Africa. Nonetheless, the thesis reveals that most of the shortcomings contained in the Securities Services Act 36 of 2004 were duplicated in the Financial Markets Bill and the Financial Markets Bill 2012. In light of this, it remains to be seen whether the market abuse provisions contained in the Financial Markets Bill and/or the Financial Markets Bill 2012 will improve the combating of market abuse practices in South Africa. Consequently, it is hoped that the relevant market abuse provisions of the Securities Services Act 36 of 2004, the Financial Markets Bill and/or the Financial Markets Bill 2012 will be comprehensively reviewed in regard to the recommendations made in this thesis. To this end, the thesis proposes a viable anti-market abuse model and policy framework and sets out both policy objectives and provisions which policy makers could use to strengthen some of the market abuse provisions in South Africa.

- Description: This dissertation presents a critical study of voice teaching method as this pertains to the high school learner studying voice within the South African educational environment, with learning outcomes determined for subject music within the GET (General Education and Training) and FET (Further Education and Training) bands of the Department of Basic Education at each school grade level, as well as by external examining bodies such as Unisa (University of South Africa), Trinity Guildhall and ABRSM (Amalgamated Board of the Royal Schools of Music). Emphasis is placed on the methodological principles applicable in the case of the Western classical music solo vocal repertoire, but reference is also made to the applicability of this method in other vocal genres and, in particular, in the case of choral music participation. Special attention is given to the subject of the vocal health of the developing teenage voice, which includes an overview of vocal disorders and suggestions for rehabilitation and remedial programmes where necessary. Triangulation of research results is achieved in this study through inclusion of: - A thorough survey of selected pertinent bibliographic sources - Description of and engagement with the researcher’s own numerous phenomenological encounters in this field - Interviews conducted in Port Elizabeth with Jill Nock, voice teacher, on the subject of voice teaching method, and with John Black, Ear, Nose and Throat Specialist, on the subject of vocal health. The researcher concludes that there is a need for continued education and training of music educators in the South African high school environment, many of whom are not trained voice specialists, in order to cater for the growing number of high school music learners who choose to specialise in voice. Although educator networking can go a long way towards creating an informal support system to address this need, it is ultimately the responsibility of the Department of Basic Education to address this in a formal and all-encompassing fashion.

- Description: The use of electronic services results in the generation of vast amounts of Online Resource Usage (ORU) data. ORU data typically consists of user login, printing and executed process information. The structure of this type of data restricts the ability of decision makers to effectively and efficiently analyse ORU data. A data warehouse (DW) structure is required which satisfies an organisation’s information requirements. In order to design a DW structure a methodology is needed to provide a design template according to acknowledged practices. The aim of this research was to primarily propose a methodology specifically for the design of a DW structure to support the efficient and effective analysis of ORU data. A variety of relevant DW structure design methodologies were investigated and a number of limitations were identified. These methodologies do not provide methodological support for metadata documentation, physical design and implementation. The most comprehensive methodology identified in the investigation was modified and the Adapted Triple-Driven DW Structure Design Methodology (ATDM) was proposed. The ATDM was successfully applied to the information and communication technology services (ICTS) department of the Nelson Mandela Metropolitan University as the case study for this research. The proposed ATDM consists of different phases which include a requirements analysis phase that was adapted from the identified comprehensive methodology. A physical design and an implementation phase were included in the ATDM. The ATDM was successfully applied to the ICTS case study as a proof of concept. The application of the ATDM to ICTS resulted in the generation and documentation of semantic and technical metadata which describes the DW structure derived from the application of the ATDM at a logical and physical level respectively. The implementation phase was applied using the Microsoft SQL Server integrated tool to obtain an implemented DW structure for ICTS that is described by technical metadata at an implementation level. This research has shown that the ATDM can be successfully applied to obtain an effective and efficient DW structure for analysing ORU data. The ATDM provides guidelines to develop a DW structure for ORU data and future research includes the generalisation of the ATDM to accommodate various domains and different data types.

- Description: The objective of the study is to investigate and compare the 2010 first year intake students’ profile, for the NMMU Business School MBA programme with their module success rate against success indicators derived from previous literature and the SHL tests results in order to compile a conceptual framework as a guide to analyse the database used. The MBA success indicators, as provided in previous literature, were analysed by addressing the following: The psychometric tests as predictors of success; Age as a predictor of success; Cultural background as a predictor of success; Work experience as a predictor of success; and, Educational background as a predictor of success. The NMMU Business School MBA students’ historical data were used as a database for this study. The module pass rates were collated as part of the database, which included the students’ biographical information. The results of the SHL test battery used as the entrance test for admission could not be obtained as the information is regarded as confidential given that the nature of the assessment data requires certain training qualifications from users; and SHL South Africa was approached to collaborate on this study. SHL South Africa performed the statistical analysis and provided these for interpretation and use in the study. The study revealed that more than half of the NMMU MBA candidates did not complete the programme in the minimum prescribed period, as only 40.5 percent of the candidates completed successfully all modules in this period, and 52 percent of them were in the 30 -39 years-age category. It also revealed that 78.1 percent of those that had successfully completed the programme were males compared with the 21.9 percent of females that completed the course. The study showed that in the 59.5 percent of those that were not successful, 40.4 percent were females compared to 59.6 percent of unsuccessful males in the same sample. Although the pass rates ranged above 75 percent, only one module had the full sample writing the examination, and the lowest core module had 67percent candidates writing the examination. The current entrance process is recommended with improvements to increase the pass rates, throughputs, and to allow for a stricter analysis of the entrance test results.

- Description: This dissertation is a self-reflexive study into effective translation strategies. The study focuses primarily on the translation strategies by Vinay and Darbelnet (1995), namely direct and oblique strategies of translation. The strategies are used in the translation of Jeanne Goosen‘s novel Louoond (1987). The novel was chosen on account of the writer‘s unique writing style and the challenges it poses for the prospective translator. One of the key objectives of this study was to comprehensively illustrate Vinay and Darbelnet‘s strategies of translation when translating the novel. The theoretical framework of this study is an analysis of Vinay and Darbelnet‘s translation strategies. The study also aims to give insight into what is meant by translation, translation theory, literary theory and literary translation. The translation of the novel is the final product, but in order to illustrate each procedure of Vinay and Darbelnet (1995) examples were taken from this final product. The chapters that follow illustrate the strategies of Vinay and Darbelnet (1995) as used in the translation of an Afrikaans text (SL) into English (TL). Conclusions can then be drawn as to whether full equivalence was obtained and whether the translation is deemed successful.

- Description: Wild edible plants are an indispensible part of diets in some of the poor resourced rural societies. In many less resourced households a main meal comprises of a starch staple which is accompanied by a supplement of vegetables that provide the other nutritional elements as well as flavour to the meals. The vegetable relish (isishebo) thus, becomes an important component of the diet. The sustenance of many such resource poor indigenous societies over many generations has been as a result of their reliance on a readily available supply of their nutritional requirements, where edible wild plants formed the major food source. Wild edible plants provided the most important source of nutritional supply even during times of drought and famine. However, lifestyle changes have caused a serious reduction of the gathering and use of the wild edible vegetables, knowledge about them and the local culture are also lost with them. Unfortunately, others have come to regard their traditional food resource base as primitive and inferior and have come to rely on new exotic food plant whose supply is unstable and narrow compared to the wide variety of wild edible plants. Even when drought challenges play destruction with food availability, resulting in food shortages due to the reliance on cultivated crops that are poorly adapted to local conditions, communities cannot go back to the unknown food plants. However, detailed scientific investigations are needed to understand and preserve wild food uses. This study was undertaken to add to that body of knowledge. It started with an ethnobotanic survey of the use of wild food plants in 10 selected rural villages and peri-urban dwellings in the Amathole District of the Eastern Cape. These rural areas were chosen because of the belief that there are still individuals who possess the wealth of traditional knowledge within those remote areas in addition to that the villages are surrounded by indigenous vegetation from which they could be harvesting some indigenous food plants. Furthermore, the relationship between people and plants are often clearer in indigenous/traditional societies since the link between production and consumption is more direct. Besides the survey, this research employed various methods including Inductively Coupled Argon (ICP) analyses of minerals and vitamins, determination of phytochemicals and antioxidant/bio-activity that of, higher performance liquid chromatography (HPLC) determination of other vitamins, assessment of proximate and anti-nutrient compositions of raw and cooked samples of plants, scanning electron microscopy (SEM) and energy dispersive x-ray spectroscopy (EDXS) to look into the micro-morphology of leaves for details that might have a bearing in the nutrient composition of the wild edible vegetables. This was done with the aim to explore and highlight the wild-food-plant base of indigenous people, to investigate the nutritional value of the selected frequently consumed wild vegetables and to recommend ways of educating people on the value of such plants and the need to promote their continued sustainable use as well as preservation of them for the benefit of people who cannot afford a continuous nutritious meal particularly among rural communities. Twenty-five (25) indigenous wild food plants which included leafy vegetables, nuts and fruits species were identified as being arbitrarily gathered and utilised as food, of which seven wild leafy vegetable species were often mentioned as common among the 15 dwellings surveyed and most frequently consumed by the respondents. Two additional plants were also frequently used as flavoring and in their raw state respectively. Wild edible vegetables were mainly eaten boiled as ‘laxa’, mixed with maize meal as ‘imifino’, fried as relish ‘isishebo’ or raw for both snacking purposes and medicinal functions. Wild edible plant species in the Amathole District of the Eastern Cape-South Africa were documented with respect to their uses and knowledge or identification. Four indigenous wild vegetables (Chenopodium album, Solanum nigrum/nodiflorum, Amaranthus dubius and Urtica lobulata) frequently consumed by the indigenous communities in the study region were selected. All the plant species had a remarkably high content of pro-anthocyanidins (between 58.42 and 65.18 mg/g) and also exhibited high radical scavenging activity in vitro. S. nigrum and C. album were found to be rich sources of ascorbic acid, having 1.05mg/100g and 1.01mg/100g, respectively. The entire wild, traditionally edible plants contain reasonably good concentrations of riboflavin while U. lobulata was found to contain maximum amount of thiamine. All plant species were rich sources of minerals and vitamins (both water soluble and fat soluble). Appropriate cooking methods are to be used to enhance the bio-availability of vitamins and nutrients in general. Cooking generally improved the nutritive value in certain wild vegetables. However, some nutrients were drained away. For example micro-nutrient and anti-nutrient component in the ash were reduced in cooking. The EDXS analysis has shown that the indigenous, wild vegetables in the Amathole District of South Africa are excellent sources of minerals, while the mineral crystals present at the level of the mesophyll of the indigenous wild vegetables were probably mixtures of calcium oxalate, calcium sulphate and silica. Saponin, tannins, oxalates, phytates and alkaloids are present in all the indigenous wild vegetables, but in minimal safe quantities. Nutritional analysis of some wild food plants demonstrates that in many cases the nutritional quality of the plants is comparable and in some cases even superior to domesticated exotic varieties. Knowledge about gathering and use of some wild food species is common among the rural dwellers. However, most uses are known by few elderly informants only. Education, awareness campaigns and revival of use of wild edible plants directed at the youth particularly is essential and this can be done through all forms of media. , Thesis (PhD) (Ethnobotany) -- University of Fort Hare, 2012

- Description: Invasive alien tree species have negative environmental and economic impacts throughout the world. For example, black wattle (Acacia mearnsii) threatens native habitats by competing with and so repressing or excluding indigenous vegetation: in this way it replaces grass communities, reduces biodiversity, and increases water loss from riparian zones, thereby fundamentally damaging the ecosystem. The Acacia mearnsii threat requires urgent attention: effective control and management is urgently required if these deleterious impacts are to be reversed or prevented. The present study was conducted in the Elliot and Ugie communities situated in the Sakhisizwe and Elundini Local Municipalities. The objective of this study was to design integrated, efficient and cost-effective methods to help farmers and members of these communities with control and management of alien plant invasions. Further the study aimed to evaluate the implementation and efficacy of Working for Water (WfW) initiatives in poverty alleviation, and skills development: in addition the study attempted to assess WfW inputs as regards relevant legislation aimed at combating major wattle invasions. Mixed methodological approaches were employed, utilizing both qualitative and quantitative techniques. Questionnaire surveys, semi-structured interviews, use of photos, content analyses of local documents and experimental field work were all employed in order to collect and interpret data for the study. The study reveals that mechanical control and rehabilitation in combating should provide efficient and cost-effective methods for proper management of rangelands. Moreover the National Department of Agriculture, Forestry and Fisheries (DAFF) should be urged to devise and enforce legislation that will help to ensure sustainable control and management of black wattle through conservation of the natural environment. Furthermore funds should be made available for wattle eradication programmes so as alleviate poverty by creating more job opportunities for members of poor communities.

- Description: The procurement process, from the demand formulation to the final delivery of a public building to the end-user, is defined by the government in terms of procedures and policies to be followed, which is based to be ineffective and inefficient where the process as a whole from a client-value perpective, is flawed. Presently, the National Department of Public Works(NDPW) as a governmental administration is deemed to be a controlling institution and cost centre rather than a service provider. This mind-set is reflected by the inability of government project implementing agencies such as the NDPW to deliver projects successfully in terms of cost, time, and quality whilst failing to meet the government's socio economic objectives to create employment opportunities, stimulate economic growth, and transfer skills to the previously disadvantaged through black economic empowerment (BEE) initiatives. Client satisfaction has widely been recognised by researchers as one of the key challenges for quality improvement in the construction industry. It is a vital factor in the development and management of the construction process, as well in the creation of efficient organisation-client relationship. In addition, client satisfaction is deemed to be a catalyst for client retention which is a success strategy for any organisation. This thesis is primarily concerned with project performance and service delivery by the NDPW as a government project implementing agency that involves an integrated approach that considers the entire supply chain of a construction project. The success or failure of a project is is not the effect of a single variable, or factor, but a set of variables interacting with each other to produce the final result. An extensive review of related literature that entails the analysis of publications related to the projectimplementation and construction project management realm was deemed necessary to formulate a clear understanding of the complexities of implementing projjects within the public sector. The use of systems thinking as the nucleus of the multi-methodological approach to this research was to assist in ascertaining the primary causes of the problem situation and to clarify the process of project implementation as a sub-system within the greater system of the construction industry. The success of projects depends as much on the client as it does on the implementing agencies, project managers (PMs), consultants, contractors and the suppliers of materials.

- Description: A vibrant and an efficient agricultural sector would enable a country to feed its growing population, generate employment, earn foreign exchange and provide raw materials for industries. The agricultural sector has a multiplier effect on any nation's socio-economic and industrial fabric because of the multifunctional nature of agriculture. The main objective of this study was to investigate how government expenditure on agriculture has affected economic growth in Zimbabwe from 1980-2009. The Log linear growth regression model was employed where gross domestic gross was the dependant variable and the explanatory variables are the factors which affect it which include government agricultural expenditure. The expenditures of government on agriculture were divided into three functions namely extension, credit assistance and R & D. The regression analyses were performed using Econometric-views 7 (E-views 7) statistical package. Regression was carried out on time series data for the period 1980 to 2009. The data was tested for stationarity and for autocorrelation. Problems of non stationarity of data were corrected by integrating the trending series. Results from the empirical analysis provide strong evidence indicating that agriculture is an engine of economic growth. The results from this study suggest that spending more on agricultural research and development can improve economic growth and ultimately reduce poverty. However, it can also be concluded that insufficient government agricultural expenditure on extension and credit assistance adversely affected economic growth in Zimbabwe, based on the results of the study. Global experience with pro-poor growth and empirical work spanning India, Benin and Malawi demonstrates the importance of agricultural expenditure for poverty reduction in poor rural areas, while also pointing to the need for complementary non farm sector growth. This study also proposes a simple methodology to estimate the agricultural spending that will be required to achieve the Millennium Development Goal of halving poverty by 2015 (MDG1) in Zimbabwe. This method uses growth poverty and growth expenditure elasticities to estimate the financial resources required to meet the MDG1. The study attempts to address a key knowledge gap by improving estimation of first MDG agricultural expenditure at country level.

- Description: The adoption of the Millennium Development Goal 1 (MDG1) of reducing the rate of poverty to half of the 1990-level by 2015, the advent of democracy in South Africa, among other things, have raised concerns over the potential role of the agricultural sector. There is a belief that the sector has the capacity to successfully reduce poverty among the rural masses and contribute to addressing the problem of inequality in South Africa. In line with that thinking, South Africa‘s agricultural sector has attracted considerable fiscal policy interest. For instance, South Africa‘s statistics show that public investments in agricultural development programmes have been growing. In spite of this, rural poverty is still a major concern on an overall basis. However, this might not be the case in the Eastern Cape Province and the situation might be different for each district municipality. This study assesses the linkages between public agricultural investment, agricultural growth and poverty reduction in the Eastern Cape Province. The study also addresses the question whether Eastern Cape Province is on course to meet several regional development targets. The study also aims to provide an estimate of the amount of agricultural investment required to attain the agricultural productivity growth rate which is sufficient to meet MDG1. The study reviewed the various theories of public spending, linkages between public investment and agricultural growth and how these components affect the incidence of poverty. The conventional wisdom that public expenditure in agriculture positively affects economic growth and this growth consequently reduces poverty was noted. The reviews also revealed that in many developing countries, the current level of public agricultural investment needs to be increased significantly for countries to meet the MDG1. This study employed the decomposition technique and growth elasticity of poverty concept to estimate the response of poverty to its key determinants. The size of public spending, prioritization of public spending and the intensity in the use of public funds emerged as important in increasing agricultural production. The relationship between government investment in agriculture and agricultural GDP shows iv that public funds were largely behind the province‘s success in increasing agricultural production throughout the period from 1990s to 2010. Agricultural spending went to sustainable resource management, administrative functions and then farmer support programme. Exceptional growth in the size of spending was recorded in respect to agricultural economic function, structured agricultural training, sustainable resource management and veterinary services. Overall output from the agricultural sector fluctuated, and the sector contributed less than 5 per cent to the total provincial GDP. Correlations between growth in agricultural sector and changes in the incidence of poverty in Eastern Cape show that during the period 1995 to 2000, increases in the agricultural GDP per capita may have failed to benefit the poor as poverty increased in all the reported cases.–However, for the period between 2005 and 2010, the situation was different and it was observed that increases in agricultural GDP per capita and were associated with reduction in the incidence of poverty. Growth elasticity of poverty (GEP) estimates reveal that agricultural GDP per capita was more important in reducing poverty in 5 out of the 7 district municipalities. Non-agricultural GDP per capita was only important in two district municipalities. It emerged that most of the district municipalities are not in a position to meet any of the regional set goals. This situation is largely attributable to the province‘s failure to boost agricultural production which is an outcome of low and inefficient public expenditure management, inconsistent and misaligned policies and failure to fully embrace the concept of pro-poor growth. Varied provisional estimates for the required agricultural growth rate and the increase in public spending on agriculture required in order to reach MDG1 were calculated for each district municipalities. All the district municipalities of Eastern Cape will need to increase public investment in agriculture for them to achieve MDG1.

- Description: The focus of this study is the Southern African Development Community (SADC) preventive diplomacy interventions in Lesotho in 1994, 1998 and 2007. The core aim of the study was to evaluate the efficacy of the SADC security mechanism (the Organ on Politics, Defence and Security (OPDS) in conflict prevention, management and resolution on the basis of the Lesotho experience. Data for this qualitative case study was collected through interviews and document analysis. The twenty four participants for the study were drawn from the SADC OPDS unit, Lesotho political parties, Civil Society Organisations (CSOs), Academics from the University of Botswana (UB) and the National University of Lesotho (NUL), retired Botswana Defence officers who participated in the Lesotho missions and office of the post-2007election dispute dialogue facilitator in Lesotho. Documents on the SADC Treaties, Protocols, Communiqués and interventions in other set ups were used to highlight its operational policies, mandate, structures, successes and challenges. Lesotho was chosen as a case study because SADC employed both non-coercive (SADC Troika and Eminent Person mediation, 1994 and 2007 respectively) and coercive measures (the 1998 military intervention). The findings of the study revealed that SADC as a regional body had its own successes and challenges. Different perceptions on the SADC interventions in Lesotho emerged mainly between the participants from the ruling party and the opposition parties. While the former commended SADC for successfully mitigating the calamitous effects of 1994, 1998 and 2007 post-electoral violence, the opposition parties viewed the regional organisations as engaged in illegal interference in the domestic affairs of the country to defend the incumbent governing party. It also emerged from the study that the SADC security mechanism has numerous structural and operational flaws. There were several unanswered questions revolving around the legality and mandate of some of the missions. For instance, no concrete evidence emerged as to whether the 1998 military intervention was authorised by the SADC. The study also revealed that SADC has learnt valuable lessons from the Lesotho missions. Some of the reforms which the SADC has introduced in the OPDS such as the establishment of the SADC Stand by Force, Early Warning structures, the Mediation Unit, and a panel of expert mediators emanated mainly from the Lesotho experiences. The study recommends that SADC needs to harmonise the efforts of its OPDS structures such as the Mediation Unit; the Troika; the Inter-State Defence and Security Committee (ISDSC); the Inter-State Politics and Diplomacy Committee (ISPDC) and the Summit of Heads of States and Governments for rapid, coherent and well coordinated interventions in future regional preventive missions. It is also recommended that SADC should focus on identifying and mitigating underlying causal factors such as underdevelopment; poverty; deprivation of freedoms, marginalisation and other forms of social stratifications and oppression in its preventive diplomacy missions if durable peace is to be achieved in Lesotho and any other future cases.

- Description: Among the world‘s ecosystems, estuaries have the highest total economic value per hectare. They are dynamic coastal biomes that provide a host of different goods and services to the surrounding terrestrial and aquatic environments and the people who utilise them. These goods and services include, inter alia, nursery areas for marine organisms, harvested natural resources (such as fish, shell-fish, bait organisms, reeds and mangroves), flood attenuation, water purification, nutrient and sediment sinks, waste disposal, transport, aesthetic beauty and areas for swimming, boating and fishing. Assessing the condition of estuaries is difficult as their state can change depending on what is being measured. Assessments have been carried out on the health of estuaries in South Africa with the results of these studies being used as inputs to the process of assessing the minimum water supply requirements for each estuary (ecological reserve) in order to maintain or improve its functionality. These ecological reserve requirements are assigned using Resource Directed Measures (RDM). These measures, however, have been criticised for being highly complex and too costly to implement for all South African estuaries within a reasonable time period. Another concern is that the levels of demand for recreational goods and services provided by the estuary are not taken into account when assessing estuarine value. It is important to understand that the use of estuaries for recreational purposes is inextricably linked to their health and sound ecological functioning. Although South African estuaries have been quite well buffered from impacts until only very recently, their use and pressures have escalated faster than what conservation authorities and policy makers have been prepared for over the last couple of decades. There is thus mounting pressure on estuaries as recreational outlets, which, in turn, has led to their functional deterioration as well as deterioration in the quality of the recreational experience as a whole. One implication for management is that more and more trade-offs have to be made in an attempt to balance the conservation and recreational use of estuaries.

- Description: Human-wildlife conflict frequently involves carnivores, mainly because of their large home ranges and dietary requirements. As such, carnivores tend to be the first animals to be lost in human-dominated ecosystems. This is significant because the removal of carnivores can alter the functionality of ecosystems. However, the conservation of carnivores depends as much on the socio-political and socio-economic landscapes as it does on the ecological one. The consolidation of vast, un-fragmented conservation areas in Africa and the world is unlikely. Thus, unravelling the factors (both biological and sociological) responsible for and influencing human-predator conflict is critical for carnivore conservation. The Winterberg district in the Eastern Cape, South Africa has been a sheep (Ovis aries) farming stronghold for nearly 200 years. Consequently, conflict between farmers and predators is commonplace and depredation of livestock by caracals (Caracai caracal) remains a perennial problem. However, the extent of this human-predator conflict (including a reliable assessment of caracal density) has not been quantified. This study used camera trapping to estimate the density of caracals (a nonindividually recognisable species) in the Winterberg and a structured questionnaire to gauge the general attitudes of the farmers of the region. Caracal density was estimated to be 0.20 caracals/km². This estimate equates to a population of approximately 54 caracals across the entire district. Therefore, caracals do not appear to occur at high densities in the Winterberg. However, the survey of the residents of the Winterberg Conservancy revealed that predators were rated as the greatest problem faced by farmers in the area. Although not significant, it also showed that the size of a respondent's property and sheep mortality due to caracals had the greatest probability of affecting attitudes towards predators. The farmers lost less than 10% of their stock to caracal depredation on an annual basis. Therefore, the general perception that predators were the most important factor in stock loss in the area does not appear to be fully supported by my data. The Winterberg is a male-dominated, multigenerational society and it is likely this propagates certain perceptions towards predators which are a reflection of long-held family traditions and beliefs. Such situations can result in reactions which are disproportionate to the actual scale of the problem. However, my study was limited to a sub-set of the landowners in the Winterberg. Thus, more intensive assessments of caracal space use and community attitudes towards predators are recommended.

- Description: An ecosytem-based spatial conservation plan for the South African sandy beaches. Sandy beaches are valuable ecosystems. They support a collection of species that is unique, comprising many endemic species, and provide a number of key ecosystem goods and services, including scenic vistas for human recreation, nesting sites for turtles and birds, and important areas for biogeochemical recycling, water filtration and purification. However, sandy beaches have not been well understood or appreciated as ecosystems, and consequently have a legacy of poor coastal management. In many instances this has lead to a "tyranny of small decisions", where multiple, seemingly insignificant management decisions and actions have resulted in complete transformation and degradation of the shoreline in several places. In addition to inappropriate management strategies, beaches are also poorly represented in conservation areas. Further, where they are recognised as being "conserved" in marine protected areas, this often is a false sense of protection because the far more sensitive dune portion of the littoral active zone is invariably not included in the reserve. In short, there is a need for a new way to approach sandy beach conservation and management that includes the system (dunes, intertidal beaches and surf zones) as a whole. On one hand, the approach should make provision for use of the abundant natural resources and opportunities associated with sandy shores in ways that are sustainable and contribute to biodiversity stewardship - through ecosystem-based management and marine spatial planning. But, on the other hand, it must simultaneously contribute to securing a sufficient amount of the key ecological attributes of beaches (habitats, biodiversity and processes) in a network of reserves, to ensure that the ecosystem, natural resources, and services all persist in perpetuity - through systematic conservation planning. The aim of this Thesis is to integrate these into a single approach, which I call ecosystem-based spatial conservation planning for sandy beaches, using the South African sandy shores as a case study. To achieve this broad aim, the Thesis is divided into three parts. Part 1 deals with establishing baseline information by quantifying spatial patterns in sandy beach habitats (Chapter 1), biodiversity, key assemblages and processes, and outstanding physical features (Chapter 2). First, mapping sandy beach habitats is a challenge given the vast, linear extent of shorelines and significant resources required to complete the project. Therefore, a novel approach was derived using statistical techniques (conditional inference trees) to identify physical features of beaches that can be observed on Google Earth (or similar) imagery, and that can provide good predictions of beach morphodynamic (habitat) types. Based on the results of this analysis, sandy beaches (and all other coastal habitat types) were mapped digitally in ArcGIS. Second, spatial patterns in sandy beach biodiversity (vertebrates, macrofauna, microflora and foredune plants) were mapped by compiling existing data on the distributions of key species that have been well studied or mapped previously (vertebrates and foredune plants), and by niche modelling (macrofauna and microflora). For the latter, data from all previous sandy-beach sampling events in South Africa were compiled from published and unpublished sources, and supplemented with additional sampling of 23 beaches along the national shoreline, targeting macrofauna and phytoplankton. Altogether, the macrofauna database comprised data from 135 sites and 186 sampling events, and the microflora (phytoplankton and microphytobenthos) database comprised data from 73 sites and 510 samples. The probabilistic distribution of each "resident" species (present at 10 or more sites) was modelled in MaxEnt version 3.3.3k, probability thresholds were determined statistically (to convert the data into predicted presence-absence), and displayed as a digital map. A composite biodiversity map was compiled, and key trends in species richness and endemism along the national shoreline were quantified. To supplement biodiversity proper, additional valued-features of sandy beaches were mapped, including: important assemblages; unique habitat features; and sites associated with key ecological processes. Part 2 considers threats to sandy beaches in the context of deriving an appropriate management strategy that seeks to provide for use of the coast, but in a way that has least overall impact to the ecosystem. A method for assessing cumulative threats to sandy beaches is adapted from an existing framework (Chapter 4). This entailed compiling a list of threats to beaches, and scoring these (out of 10) in terms of the severity of their respective impacts to beaches, and how long it would take the ecosystem to recover should the threat be removed. The scoring was based on the collective expert opinion of the scientific community working on sandy beaches, at a workshop during the VIth International Sandy Beach Symposium 2012. To standardize the scores and ensure broad applicability, a base case scenario of a pristine beach was established, and maximum theoretical scores were provided for this context. The method for integrating these scores into a spatial, cumulative threat assessment was then determined. In Chapter 5, the maximum theoretical scores (from Chapter 4) were down-scaled to suit the current threat regime to the South African sandy beaches, and the cumulative threat assessment methodology was applied. From this analysis, the most threatened beaches in South Africa, and the most important threats were highlighted. A decision-support tool for managers was derived from the site-specific cumulative threat-impact scores, based first on the degree of permanent habitat transformation, and second on the cumulative impact of other stressors where the impacts these stressors have could potentially be mitigated or ameliorated. Part 3 concerns conservation of beaches explicitly. It addresses how much of which valued features of beaches is required to ensure their long-term persistence, and the design of a network of beaches in South Africa that are of ecological importance and should be set aside as reserves. Conservation targets are set in Chapter 6, using species-area curves to determine a baseline percentage-area required to protect sandy beach habitats, which is modified using heuristic principles based on habitat rarity and threat status (from a recent national assessment). A fixed target was applied to all species, also modified by heuristic principles, and another fixed target was applied to key assemblages and processes.

- Description: This study sought to determine whether or not it may be possible to evoke ‘the musical effect' – the emotional response perceived by music listeners – using white noise as a sound-source and real-time digital signal processing techniques. This information was considered to be valuable as in a world driven by technological progress the potential use of new or different technologies in creating music could lead to the development of new methods of – and tools for – composition and performance. More specifically this research asked the question 'what is music?' and investigated how humans – both trained musicians and untrained people – perceive it. The elements of music were investigated for their affective strengths and new fields of research explored for insights into emotion identification in music. Thereafter the focus shifted into the realm of Digital Signal Processing. Common operations and techniques for signal manipulation were investigated and an understanding of the field as a whole was sought. The culmination of these two separate, yet related, investigations was the design and implementation of a listening experiment conducted on adult subjects. They were asked to listen to various manipulated noise-signals and answer a questionnaire with regard to their perceptions of the audio material. The data from the listening experiment suggest that certain DSP techniques can evoke ‘the musical effect’. Various musical elements were represented via digital techniques and in many cases respondents reported perceptions which suggest that some effect was felt. The techniques implemented and musical elements represented were discussed, and possible applications for these techniques, both musical and non-musical, were explored. Areas for further research were discussed and include the implementation of even more DSP techniques, and also into garnering a more specific idea of the emotion perceived by respondents in response to the experiment material.

- Description: The government established school Governing Bodies through the South African Schools ACTS NO 84 OF 1996. The aim of this Act was to inter alia ensure greater parental involvement in school management. The good relationship between the school and the community at large is important for the growth and development of a child. It was for that reason that the national department of education introduced a three legged body called SGB, which is composed of Parents, Teachers and Learners to govern the schools. In this study the researcher investigated the nature of relationship among the SGB components in rural schools. A case study was conducted at rural senior secondary school in the Libode Mega District‟. The purpose of this study was to investigate the relationship among SGB components that are parents, teachers and learners in research school. This study would help in creating an understanding of the importance of good relationship among SGB components. The one broad research question was: What is the nature of relationships among the SGB components (parents, learners, and teachers) of the research school towards attainment of school goals? This was a case study using interviews, documents such as SGB minutes, notices of SGB meetings as an instrument for research. The sample represented all parents, learners and teachers who were SGB members in the research school. For purposes of validation the questionnaire was piloted to different schools with a similar situation to the research school. The data gathered were analysed qualitatively and findings and recommendations formed the most vital component of the dissertation. Findings were as follows: The SGB of the research school knew about their roles and responsibilities. SGB meetings were Organized and run properly. There were good Relationships among SGB components. Management of school finances was good and transparent. There were standing meetings for reporting to constituency.
