  • Description: Skills transfer to Municipal employees is lacking due to management delays in acknowledging and understanding its importance to the affected employees. These result in poor work performance and services delivery to the communities. In the research design the Job Performance in any organisation is expected to be releasing good results or outcomes. Employees expect to be recognised in their work they perform. The employers’ responsibility is to ensure that the employee’s interests are taken care of reasonably. Scarce skill is a very important aspect in the career of specialised skilled employees and expectations are very high in this kind of environment. Globally the scarce skill is one of the aspects that is encouraged that organisations should take cognisance of. When staff is recruited and works for the Municipality it is vital that they are retained and capacitated through trainings. The employees that have worked for the Municipality a longer period should or must at least transfer those skills for the preparation of the succession planning and continuity in the organisation. The data was collected in a form of a questionnaire where respondents indicated their responses based on the questions formulated to measure their job performance, scarce skills, retention of staff, recruitment and selection, on-the-job training for skills transfer and training in relevant field. The data collected was analysed and presented in the form of tables and percentages. The study has revealed that the clear strategies recommended are essential in the personal development of employees through training, recognition inthe institution by way of remuneration or awards and ensuring to retain staff for a longer period for succession planning in a municipal environment.

  • Description: The purpose of this mini-dissertation is to understand the perception of end users on the public procurement system challenges in the Eastern Cape Department of Transport, addressing the extent to which the procurement systems have resulted in disgruntlement of end-users. The public sector procurement function continues to face growing pressures to reform current procurement process, the reform comes with changes which some public officials are unable to adapt to. The uncertainty and the complexity of the reforms to a certain extent bring resistance to the end users whose concern is to meet delivery targets for a particular financial year. Public procurement is still faced with somewhat of an “identity crisis”, people still see the function as clerical or technical in nature. The remaining challenge is to convince these individuals that procurement is a strategic function. This study however, seeks to investigate the level of understanding of procurement prescripts and relevant legislations by end users and the unnatural working relationship with SCM office.

  • Description: A follow-up of traditional medicinal plants uses is an important tool in highlighting their therapeutic potentials, as they have been found to be a source of a wide range of bioactive compounds that can be used as base compounds for new pharmaceutical drugs. This study therefore focuses on assessing the anti-Listerial properties of the seeds of Garcinia kola (Heckel) plant, which is a traditional medicinal plant of west and central African origin, and was and is still used to traditionally treat several ailments. Four different solvents crude extracts of the seeds were assessed for their anti-Listerial activities in-vitro, against a panel of 42 Listeria bacteria, which included Listeria monocytogenes, Listeria ivanovii and Listeria grayi species. At 10 mg/ml concentration the aqueous extract had activity against 29% of the test isolates while the other three crude extracts namely dichloromethane, n-hexane and the methanol extracts had activity against 45% of the test bacteria. The minimum inhibitory concentration (MIC) ranges of the extracts were 0.079-0.313 mg/ml for the dichloromethane extract; 0.079-0.625 mg/ml for the n-hexane extract; 0.157-0.625 mg/ml for the methanol extract; and 10->10 mg/ml for the aqueous extract. The minimum bactericidal concentration (MBC) ranges of the extracts were 0.625–10 mg/ml for both the n-hexane and the dichloromethane extract; 5-10 mg/ml for the methanol extract; and those for the aqueous extract were above 10 mg/ml against all the susceptible Listeria isolates. The rate of kill analysis was then determined for the three most active crude extracts that is excluding the aqueous extract and it was assessed against four representative Listeria species namely L. monocytogenes (LAL 8), L. grayi (LAL 15), L. ivanovii (LEL 30) and L. ivanovii (LEL 18). All the three extracts showed a general trend of being concentration and time dependent in their rate of kill profiles such that most bacteria cells were killed at the highest test concentration of 4× MIC value after the maximum exposure time of 2 h. The n-hexane, dichloromethane and methanol extracts were bactericidal against 4, 3 and 1 isolates out of the four test Listeria isolates respectively.

  • Description: Lake Liambezi in the Zambezi Region of Namibia, formerly known as the Caprivi Region, is shallow (<6m deep) and characterised by cyclic episodes of filling and drying. When full the lake supports a highly productive fishery and when dry the lake is completely dry and used for agriculture and grazing. In 2000 the lake filled, and between May 2011 and April 2012 was surveyed using beach seine, experimental gillnets and catch landing surveys to obtain information for conservation and management recommendations for the fishery. Littoral fishes in Lake Liambezi and the Kavango floodplain were sampled using seine net and physicochemical properties were measured. Seine net surveys demonstrated that Lake Liambezi littoral zones were dominated by fishes of the family Alestidae (59.7%) while Cichlids constituted the most diverse family. Juvenile Tilapia rendalli and Oreochromis macrochir were among the five most important species in the littoral zone, indicating that these commercially important species use the littoral zone as a nursery ground. Since T. rendalli and O. macrochir are commercially important species, because of this, it is advised that seine nets should not be used. Catch efficiency between monofilament and multifilament gillnets in Lake Liambezi offshore waters were assessed. Catch efficiency experimental fishing trials showed that monofilament gillnets catch per unit effort (CPUE) was three times higher than that of multifilament gillnets for Oreochromis andersonii, O. macrochir, T. rendalli, Serranochromis macrocephalus and Clarias spp. Oreochromis andersonii comprised over 66% of the overall CPUE for both net types combined indicating the importance of this species in the gillnet fishery on the lake. A fishery has been established on the lake with more than 300 canoes and 120 fishermen using monofilament and multifilament gillnets. CPUE was 15 kg/canoe/day and was significantly (P < 0.05) associated with monthly temperature and moon phase parameters indicating that the fishery of Lake Liambezi may be altered by climate and environmental factors. Annual catch from Lake Liambezi was estimated at 3193t with an estimated productivity of 106kg/ha, suggesting that Lake Liambezi makes a significant contribution to the fish supply in the Zambezi Region. Recommendations were made to manage the Lake Liambezi fishery by imposing restrictions on effort (number of fishing boats), gear type, mesh sizes and access. Proper fisheries management and monitoring should incorporate climatic and environmental factors such as temperature and moon phase to meet the challenges of global climatic changes as well as other environmental issues.

  • Description: The purpose of this study was to determine if monitoring and evaluation tools at a local level could help bring about sustainability of rural projects of the community based organizations thereby making the livelihoods of community members better in the Eastern Cape Province. To accomplish this objective, a case study of the training provided by Transversal Training Management Agency (TTMA) was assessed within the concept of the practice of evaluation and seeking to answer four research questions: To what extent should capacity development create sustainable managerial competencies for rural projects? Are monitoring and evaluation tools the key to sustainable projects? How will knowledge and application of M&E tools improve capacity development of CBOs? What are the policy lessons that can be derived from the application of M&E tools for the grass roots groups? The research design was in two parts namely the literature review which focuses on the roles of social change theory and program theory approaches of evaluation which is best applicable for the grassroots, then the case study of TTMA. This was a qualitative research whereby secondary data source was mainly used. The researcher was an employee of TTMA within the period of study, therefore, was able to validate information. Multiple community projects were studied using the secondary data analysis. This was necessary because of the geographic spread of the CBOs that were trained all around the Eastern Cape province and the language barrier would have pose a challenge to the researcher if all project members were to be interviewed. The main findings of the study shows that training was well conducted and project members gave positive feedback about training but what was absent in the training is a study of a monitoring and evaluation framework for the projects‘ members as one of the necessary managerial competencies in order for them to track progress and warning signals in the project cycle before it is too late. In conclusion some recommendations have been made amongst which is a practical handbook of M&E for the grassroots. This provides variety of tools that can best suit the literacy levels of project members that this study targeted. TTMA can therefore, adopt this as part of the training courses for project sustainability.

  • Description: Kwa-Zulu Natal (KZN) is mainly composed of small-scale farmers with low production capacity and knowledge (ISRADS, 2004). The general problem is the performance of smallholder irrigation schemes, issues that cause low productivity; whereas the cost of purchasing machinery is too high. In the rural areas the majority of the people are unemployed due to different reasons such as lack of employment opportunities available to them, lack of skill, and low level of education and mostly they are inexperienced. This study identifies theperformance of irrigation projects amongst smallholder sugarcane farmers in KwaZulu Natal in order to uplift the livelihood of smallholder sugarcane production as well as its sustainability.This was done on the basis of demographics, historical background and agricultural potential. This dissertation will discusses all approaches used to conduct the study. The dissertation also describes the analytical framework used in this study, namely: The research design, sampling, sample size, data, data collection procedures, model description and the specific analyses carried out to address the study objectives. The results of net values of irrigated and non-irrigated lands, the irrigating households indicated13% of sugar cane production per hector more than non-irrigators. It is clearly indicated that water/ irrigation can contribute on maximizing sugarcane yield and promotes sustainability. Improving the technology from small scale growers’ point of view, extension officers from different areas that produce sugarcane should be scheduled to attend Refresher Courses at SASRI to train them on different aspect of irrigation management and sugarcane production. When there is newly established technology, such as invention of a new variety of sugarcane that is resistant to drought and diseases. It would be more essential for agricultural development to encourage government investment on more irrigation schemes facilities.

  • Description: The production of final effluents that meet discharged requirements and guidelines remain a major challenge particularly in the developing world with the resultant problem of surface water pollution. This study assessed the physicochemical and microbiological qualities of two wastewater treatment works in the Eastern Cape Province of South Africa in terms of the prevalence of faecal coliforms and Escherichia coli O157:H7 over a five month period. All physicochemical and microbiological analyses were carried out using standard methods. Data were collected in triplicates and analysed statistically using IBM SPSS version 20.0. The ranges of some of the physicochemical parameters that complied with set guidelines include pH (6.7 – 7.6), TDS (107 – 171 mg/L), EC (168 – 266 μS/cm), Temperature (15 – 24oC), NO3- (0 – 8.2 mg/L), NO2- (0.14 – 0.71 mg/L) and PO4 (1.05 – 4.50 mg/L). Others including Turbidity (2.64 – 58.00 NTU), Free Cl (0.13 – 0.65 mg/L), DO (2.20 – 8.48 mg/L), BOD (0.13 – 6.85 mg/L) and COD (40 – 482 mg/L) did not comply with set guidelines. The microbiological parameters ranged 0 – 2.7 × 104 CFU/100 ml for FC and 0 – 9.3 × 103 for EHEC CFU/100 ml, an indication of non-compliance with set guidelines. Preliminary identification of 40 randomly selected presumptive enterohemorrhagic E. coli isolates by Gram’s staining and oxidase test shows 100% (all 40 selected isolates) to be Gram positive while 90% (36 randomly selected isolates) were oxidase negative. Statistical correlation between the physicochemical and the microbiological parameters were generally weak except in the case of free chlorine and DO where they showed inverse correlation with the microbiological parameters. The recovery of EHEC showed the inefficiency of the treatment processes to effectively inactivate the bacteria, and possibly other pathogenic bacteria that may be present in the treated wastewater. The assessment suggested the need for proper monitoring and a review of the treatment procedures used at these treatment works.

  • Description: The existence of a particular semantic agreement strategy, what I will here call Atomic Homogeneity, has been argued to determine plurality in complex noun phrases. If the denotational properties of a complex noun phrase can be distributed to its smallest, atomic subset then plural agreement is the result. This paper explores this prediction using a large-scale experiment and demonstrates that Atomic Homogeneity is a highly significant statistical effect in the data, thus validating the prediction of this strategy. In addition, this paper serves a methodological purpose by exploring the utility of large-scale data collection by peer interview. Although it might be expected that the method is noisy, this is offset by the large amount of data collected and which is more amenable to statistical analysis than smaller-scale case studies.

  • Description: The National HIV and AIDS and STI strategic plan for South Africa, 2007-2011 aims to reduce the rate of mother to child transmission to less than 5% by 2011. On the World Aids day in 2009, the Honorable President Jacob Zuma announced the intervention to improve antiretroviral therapy (ARV), access to priority group’s in order to decrease the disease burden, to address maternal and child mortality, and to improve life expectancy (PMTCT Guidelines: 2010). According to the literature reviewed, accepting attitudes may indicate better knowledge and understanding of HIV and AIDS. Marking a change in South Africa’s history of HIV the South African Government launched a major HIV Counseling and Testing program campaign (HCT) in 2010. For the PMTCT program to work and be acceptable, it needs to be known by its clients. It helps the individual to know about their status so that they make important choices for self and others. Amongst the important choices, medications for opportunistic medications, ARV’S, behavior change, etc, are included (Project Literacy 2006:40). Aim and Objectives: The study assessed the knowledge that the pregnant women have towards the prevention of mother to-child transmission which includes HIV testing, antiretroviral prophylaxis during pregnancy, labour, and post natal and feeding options. Methods: A quantitative descriptive method was used for this study. The questionnaires developed by the researcher were used for data collection. The items on the questionnaire were divided into four (4) subsections. The questionnaire was administered to all positive pregnant women coming for follow up visit and those available at the time of data collection. Conclusion: In this study evaluation of the level of knowledge and attitude of positive pregnant women with regard to PMTCT in 5 Buffalo City Municipality clinics was conducted. It was found that some of positive pregnant women have better knowledge about PMTC though there were still those that need further education. Recommendations: The service providers, who are the professional nurses, should be provided with proper training on PMTCT program to improve their standard of service delivery and to capacitate them with knowledge and skills. Integration of HIV related health aspects during assessment and treatment of pregnant women should be strengthened, as the purpose of implementation of PMTCT was to reduce mortality rate by 50%, and also to reach the 4th Millennium Development Goal of reducing these deaths by two-thirds by 2015.east london towards prevention of mother to child transmission (pmtct)

  • Description: This research situates itself in the study of stigma in mental illness. In particular, the aim is to explore the potential that art making and exhibiting has in reducing stigma for those with a diagnosis of schizophrenia. The research explores one aspect (the exhibition stage) of an "art as therapy" project. The exhibiting of one’s artwork aims to counter limiting "patient" identities by allowing those labelled as psychiatric patients to extend their self-identity to an alternative identity of the "artist". However, this idea only stands strong if the artwork created is not discriminated against as "naïve art" and is accepted or at least considered for acceptance as legitimate nonprofessional artwork. This research explores the ways in which art created by inpatients with a diagnosis of schizophrenia is received by the general art-viewing public at the National Arts Festival in Grahamstown, South Africa. The study uses a discourse analytic framework to analyse the interviews of members of the public who attended the art exhibition of patient artwork. It will examine the ways in which the public construct the artworks and how they position the makers of this art across a continuum, from patient to artist. The results of this thesis have implications for rehabilitation practices for people with a diagnosis of schizophrenia particularly with regard to opportunities to "perform" alternative identities in public spaces.

  • Description: With the world's population expected to reach nine billion by 2050, agricultural production will have to double to meet this growing demand. Hence, a need for better infrastructure to enhance farming efficiency becomes apparent. There are a number of solutions that have been developed to date that are commercially available. They range from genetically modified seeds and bio/green fertilizers to advanced farming machinery amongst others. However most of the farming equipment developed has drawbacks such as: heavy weight – this leads to reduced yields due to soil compacting; human dependency – constant monitoring and controlling is needed; light dependency – excludes usage during the night or when visibility is poor. Therefore, a possible solution will be researched to enhance the evolution of farming equipment. Furthermore, a model will be developed for testing and verifying the research.

  • Description: As an energy source coal has one of the largest agglomerations in the world. Consequently mining of coal creates large volumes of waste in the form of low ranks coals. The complex structure of coal makes it difficult for the microorganisms to degrade and relatively few bacteria and fungi have been shown to break down coal. This study aimed to investigate bacteria not previously known to degrade coal. In this study bacteria were isolated from hydrocarbon contaminated sites and inoculated in coal medium where coal served as the only carbon source. Three strains produced a yellow – brown supernatant after 14 d of incubation at 30 °C. Bacteria generating a yellow – brown coloured supernatant were presumed to possess coal degrading capabilities and the best performing of these bacterial species was identified using 16s rDNA as Bacillus flexus. Scanning electron microscopy showed that there was a close association between the bacterium and substrate coal. The close association of bacteria to substrate suggested that these organisms were able to maximize solubilisation. FT-IR spectroscopic analysis demonstrated the addition of single bonded compounds COOH, OH, CN and CH that were absent prior to bacterial interaction. The increase in oxygen rich regions indicated degradation of the coal substrate. Elemental analysis showed that there was a decrease in carbon content from 47 % to 24 % during the 14 day incubation period. Reduction in coal carbon content was assumed to be due to bacterial utilization for metabolism and growth particularly as untreated coal substrate showed minimal loss of carbon. Analysis of the residual culture medium revealed that there was a linear increase in humic-like substance concentration for 8 d, coincident with increased coal biosolubilisation and colour change. Laccase activity was insignificant, and at 13 d enzyme activity was only 5×10-3 U/L suggesting that B. flexus may use a different mechanism to degrade coal. Residual culture medium remaining after bacterial action on the coal substrate appeared to possess plant growth promoting activity. This soluble biodegradation product with characteristics similar to humic acid-like substances was shown to impact growth of radish cotyledons. Expansion of isolated radish cotyledons was enhanced by 140% when incubated in coal biodegradation product. In conclusion, this study has yielded B. flexus and two other unidentified bacteria, isolated from polyaromatic hydrocarbon contaminated soils, and demonstrated the ability of these microorganisms to degrade waste coal. Further studies to elucidate the mechanism of coal breakdown by B. flexus, synergies with other coal degrading microorganisms, and incorporation of bacterium into Fungcoal bioprocess technology is imminent.

  • Description: Many institutions and organizations are set up to with a right motive but fail to actualize their vision. This cuts across both public and private institutions across the globe. A financial institution is selected for this research because of its sensitivity; hence getting it right with a delicate institution like a financial organization will assist usage of this monitoring system by other institutions. Modern banking in Nigeria started in 1892 with the free banking era which ended when the Banking Ordinance of 1952 was promulgated. First Bank was the pioneer bank that was established in Nigeria in 1894 as the Bank of British West Africa. The establishment of the First Bank of Nigeria predates the birth of the Nigerian nation as a sovereign entity. The bank which was registered as the bank of British West Africa in 1894 has therefore evolved along the path of political, social and economic changes and developments of Nigeria from the colonial period to independence and the experience of post-independence. It thus shared, in the process of its growth, the tidal experiences of the nation which, in retrospect, were sources of strength (Ndekwu, 1994).

  • Description: Since the launch of the Biofuels Industrial Strategy in 2007 by the South African government, only a few smallholder farmers have adopted biofuels for production. The government hopes to stimulate economic development and alleviate poverty by targeting areas that were previously neglected for agriculture by the apartheid government. However, there still appears to be a lack of a clear and comprehensive policy framework for the development of a South African biofuel industry, because the proposed initiatives have not been implemented to date. There are also concerns among stakeholders that government policy is taking too long to formulate, compounding existing uncertainty in the industry. This study therefore aims to identify barriers and incentives that influence the potential adoption of biofuel crops in selected areas in the Eastern Cape Province, South Africa. The study utilised a semi-structured questionnaire to record responses from 129 smallholder farmers that were identified through a snowballing sampling technique. Descriptive statistical analysis and a Heckman two-step model were applied to analyse the data. Analysis was done using SPSS 21 and EViews 8. Results obtained showed that the variables: arable land, incentives offered, challenges faced, labour source and farm experience were statistical significant at 5 or 10 percent p value to awareness of farmers to biofuel crops. Adoption of biofuel crops was statistically related to gender, qualification, membership to association and household size. The study recommends that the Biofuels Industrial Strategy Policy be revisited in order to have a mechanism of including smallholder farmers that it aims to empower with employment and improvement in their livelihoods. The government can help smallholder farmers by addressing the challenges they face in improving their output. Furthermore, it recommends that a national study on barriers and incentives that influence the adoption of biofuel crops be carried out in order to identify other factors that may hinder the Biofuels Strategy Policy aims in empowering the disadvantaged farmers.

  • Description: Unemployment is a huge challenge for the South African government and it has been identified as an important variable in the fight against poverty and inequality in the country. The unemployment rate in the Eastern Cape Province is higher than the national unemployment rates in the country and the unemployment rate in the Nelson Mandela Bay Municipality is higher than the provincial average. The purpose of this study is to uncover the barriers to employment in Nelson Mandela Bay. Chapter one presents the rationale and background to the study including the research aims, objectives and the scope of the research. Chapter two provides an extensive literature review about the major factors that influence unemployment rates, the government inititiatives that were deployed to reduce unemployment rates in the country and the impact of labour market inflexibility on employment outcomes. Chapter three provides the research methodology followed in this study and chapter four includes an analysis and discussions of the questionnaire data. Chapter five concludes the research report with recommendations for policymakers.

  • Description: The Soutpansberg and Tuli Coalfields are both hosted in the Karoo Basin, Limpopo Province of South Africa. The Soutpansberg Coalfield is situated north of the Soutpansberg Mountain Range and has a strike length of about 200 km and width of about 80 km which is fault controlled and extends from Waterpoort in the west to the Kruger National Park in the east. The Tuli Coalfield occurs in a small intracratonic, east-west trending fault-controlled sedimentary basin with a preserved width of 80 km and length of 120 km. The east to west trend of the Tuli Coalfield parallels that of the Soutpansberg Coalfield further east, and the two coalfields link up with the north-south trending Lebombo Basin. The Tuli Coalfield occurs in the Tuli Basin, while the Soutpansberg Coalfield occurs in the Soutpansberg Basin. The two basins preserve a heterogeneous succession of the Upper Paleozoic to Lower Mesozoic sedimentary and volcanic rocks of the Karoo Supergroup. Because the area is largely covered by the Quaternary Kalahari Group sands, the stratigraphy of the succession is not as well understood as the Main Karoo Basin in South Africa. This study deals with the intra-basinal stratigraphic correlation, facies and depositional environments, petrography, geochemistry, provenance, geophysics, structural geology, diagenesis of sandstone, subsidence history and coal quality in the Soutpansberg and Tuli Coalfields. Based on the field work and detailed sedimentological analyses of over 2000 borehole data, seven facies associations (FAs) comprising sixteen major lithofacies were identified. The facies associations are: Glacial diamictite and sandstone (FA 1), Clast supported conglomerate and sandstone (FA 2), Tabular cross-bedded sandstone (FA 3), Trough and planar cross-bedded sandstone (FA 4), Fine calcareous and micaceous siltstone and mudstone (FA 5), Sandy shale/mudstone (FA 6), Laminated or thin-bedded Carbonaceous shale/mudstone and coal (FA 7). The facies associations (FA 1 to FA 7) correspond to the lithostratigraphic sub-divisions of the Tshidzi, Madzaringwe and Mikambeni Formations. The Madzaringwe Formation in this study is informally sub-divided into the Lower, Middle and Upper Members while the Mikambeni Formation is informally sub-divided into the Lower and Upper Members. Sedimentological characteristics of the identified facies associations indicate the following depositional environments: Fluvioglacial (braided streams) depositional environment (FA 1, Tshidzi Diamictite Formation); Floodplain ponds, lakes, marshes and backswamps (FA 6 and FA 7, Lower Member of the Madzaringwe Formation); Meandering and braided channels, crevasse splays, levees and crevasse channels (FA 2, FA 3, FA 4 and FA 5, Middle Member of the Madzaringwe Formation); Floodplain ponds, lakes and backswamps (FA 6 and FA 7, Upper Member of the Madzaringwe Formation); Meandering and braided channels, crevasse splays, swamps and shallow lakes (FA 5, FA 6 and FA 7, Lower Member of the Mikambeni Formation) and lastly braided channels, meandering channels, levees and crevasse channels (FA 2, FA 3, FA 4 and FA 5, Upper Member of the Mikambeni Formation). Paleocurrent directions were measured using directional structures (cross-bedding and asymmetric ripple marks). The paleocurrent analysis shows that the direction of the channels was from south-west to north-east in both coalfields. Based on the structural study and geophysical interpretations, the structural and tectonic settings of the two coalfields have been revealed, both coalfields are normal fault-bounded. The geological evolution of the Karoo strata, at least since the Upper Carboniferous, essentially follows the type model for passive continental margin terrain. Paleostress inversion techniques have been employed to interpret the stress regime of the two coalfields. The Soutpansberg Basin is characterised by W-E to ENE-WSW extension and N-S to NNW-SSE compression. The Tuli Basin is characterised by N-S to NNW-SSE compression and W-E to ENE-WSE extension. This stress field reflects the established structural trend of the two shear belts (the Tshipise and Siloam shear zones) bounding the Central Zone of the Limpopo Mobile Belt. The geophysical interpretations were focused on outlining structures, contacts and on the delineation of gravity, magnetic and radiometric signatures in areas defined as anomalous. The magnetic, gravity and radiometric data showed low amplitudes in the sedimentary strata compared to the surrounding and basement geological bodies. The E-N-E fault system has a notable signature, defining two magnetic domains on both southern and northern sides of the Soutpansberg Coalfield. The intrusive emplacements are mainly fault controlled and they trend in the same direction as the two fault systems. Jurassic volcanics (Letaba and Jozini Formations) follow a SW-NE trend, outcropping in the east (Soutpansberg Basin), producing a strong magnetic response in this area, and partly buried in the west, where magnetic intensity tends to be reduced. Petrographic and geochemical analyses of the Soutpansberg sandstones revealed immature sub-litharenite, sub-arkose and minor arkosic arenites in nature, dominated by sub-angular to rounded detrital grains, sourced from recycled orogens, craton interior to transitional continental. The sandstones of the Tuli Coalfield are classified as sub-arkoses and minor sub-litharenites and sourced from the craton interior and recycled orogen provenances. Both petrographic and geochemical results suggest a passive continental margin source. Petrographic and geochemical results of the samples of the Soutpansberg Coalfield suggest uplifted basement source areas dominated by sedimentary rocks with minor granite-gneiss rocks. The petrography and geochemistry of the Tuli sandstones suggest source areas dominantly composed of plutonic (granites) and metamorphic (gneisses and schists) rocks with a component from a sedimentary (quartz-arenites, quartzites, shales, arkoses and meta-arkoses) rocks. Diagenetic features of Mikambeni and Madzaringwe sandstones are subdivided into early, middle and late stages. Time is relative with the earliest diagenetic event occurring shortly after deposition and the latest occurring up until present time. The main diagenetic processes that have affected the sandstones include mechanical compaction, cementation and the dissolution of framework grains and cements. Early diagenetic processes include mechanical compaction, silica and calcite cementation, clay minerals (pore lining and pore-filling kaolinite, illite and smectite), feldspar authigenesis and the formation of hematite cements and coatings. Late diagenesis includes quartz and feldspar overgrowths, seritisation, chlorite alteration, grain deformation, pressure-solution and fracturing and albitisation. The subsidence of the basins is believed to be initiated and thermally controlled by tectonics (i.e. faults of basements blocks) rather than sedimentary burial. The subsidence within the basins supports the primary graben system which must have been centered within the present basins, and later became a region of major faulting. This gave way to the Late Carboniferous rapid subsidence, with areas of greater extension subsiding more rapidly. The Early Permian (last phase) is characterised by a slow subsidence representing the post-rift thermal subsidence. The rift flanks were gradually uplifted and, and then generally subsided as a results of thermal contraction after the extension terminated. Based on the coal analysis, both coalfields are characterised by coking bituminous coal. The study has revealed that the eastern Soutpansberg Coalfield is likely to present better opportunities for identification of potentially exploitable coal deposits as compared to the Tuli Coalfield.

  • Description: This critical realist thesis seeks to understand how student, graduate and professional identities emerge in Emergency Medical Science (EMS) students at a South African University of Technology (UoT) as well as in professional paramedics in the Emergency Medical Care Services (EMCS). It further considers the construct of graduate attributes (GAs) and its relationship to emergence of identity and influence on curriculum design. The research design is that of a case study. The theoretical framework is critical realism whose depth ontology posits three domains of reality. Causal powers and generative mechanisms exist in the Real domain which cause events or phenomena to emerge in the Actual domain that are experienced in the Empirical domain. Using retroduction one may come to explore some of the causes for the event. Using Bhaskar’s concepts of identity, the self, absence and emergence, ontology and four-planar social being, a Bhaskarian explanatory framework of identity to explore the emergence of identity has been created. In exploring graduate attributes, a critical realist question is posed: “What must the world be like for GAs to exist” to explore the possibilities of the existence of GAs. It was found that student identity emerges diachronically in three moments, while professional paramedic identity starts to emerge during the third year of study mainly through the structure, culture and agency of workplace-based learning. In answer to the critical realist question it was found that GAs emerge from the neoliberalist commodification of universities. In seeking an alternative to GAs, traits and attitudes were explored. It was found that these emerge from curriculum, interplay of departmental structure, culture and agency of and from students’ being which makes them ontologically radically different from GAs. This study concludes that student, graduate and professional identities emerge from a person’s core constellational identity diachronically within four-planar social being and the interplay of structure, culture and agency. GAs cannot be related to the emergence of identity and curriculum design because of their ontology; however, if traits and attitudes are substituted for GAs, a close relationship does exist between emergence of identity, traits and attitudes and curriculum design.
