- Description: Introduction: With batting in cricket, there is no known end point, making the allocation of resources and the development of a suitable pacing strategy more difficult. How batsmen allocate resources and pace themselves when repeatedly sprinting between the wickets is therefore not known. According to the ‘anticipatory feedback’ model, the level of expertise/experience has a substantial influence on the development of a suitable pacing strategy. Skilled or experienced batsmen may therefore have a greater ability to develop and implement a pacing strategy compared to that of novice or less-skilled batsmen. Purpose: To assess whether the absence of a known end point at the beginning of repeated sprint bouts between the wickets effects how batsmen pace themselves comparing skilled and less-skilled batsmen. Methods: Twenty-four male cricketers from a university league were selected. Twelve skilled batsmen (players in the top five batting order), and 12 less-skilled batsmen (players in the bottom five batting order) completed three experimental. All trials required batsmen to complete the same number of shuttle sprints (14 shuttles and therefore 28 runs), while only the information provided before each trial differed. Control Trial: This trial is also referred to as the ‘informed’ trial as the batsmen are aware of the exercise requirements (end point). Unknown Trial: The batsmen were not informed of the exercise end point and were required to run on command for an indefinite period (28 runs). Deceptive Trial: Batsmen’ were incorrectly informed with regards to the number of sprints (told they were only doing 14 runs when in fact they were doing 28 runs). Muscle activity, sprint times and RPE measures were obtained during all three trials and compared. Results: Significant (p<0.05) group effects were apparent for sprint times and, ‘central’ and ‘local’ RPE. Specifically, skilled batsmen obtained the faster mean sprint times, and less-skilled batsmen reported the higher mean ‘central’ and ‘local’ RPE values in all three experimental trials. There were no significant group effects for muscle activation. Skilled batsmen did however have lower muscle activation compared to less-skilled batsmen in all three trials. Furthermore, general trends revealed that sprint times and muscle activation decreased over time (from shuttle 1 to shuttle 14), and RPE (‘central’ and ‘local’) ratings increased, regardless of the experimental trials. Skilled batsmen performed the best in all three trials. This was determined by the attainment of faster sprint times, lower muscle activation and low RPE ratings in each of the three trials. The assessment of the relationship of the dependent variables measured in each trial, did however suggest that skilled batsmen performed best in the deceptive trial while less-skilled batsmen performed best in the control trial. Skilled batsmen thus showed superior performance when trial requirements were unclear. Less-skilled batsmen however, were seen to experience decrements in performance when information regarding the end point was unknown or misleading. Conclusion: It can thus be concluded that previous experience facilitates in the obtainment of improved sprint times between the wickets, especially when the exact end point is unknown.

- Description: This qualitative case study was undertaken in order to explore the experiences of drum set students who apply themselves to James Dreier’s Standard Tune Learning Sequence (STLS) in a self-directed learning environment. These experiences ultimately shed light on how best to implement Differentiated Instruction to the STLS. The study draws on the experience of three adult drum students under the instruction of the author. The students were provided with the STLS and left to proceed with it on their own. They were asked to keep a record of their progress in the form of a learning journal. These learning journals were used, in conjunction with transcribed interviews and learner profiles, as data for this study and as such were subjected to Interpretative Phenomenological Analysis. The study recognizes three factors which affect the student’s successful progression through the STLS: readiness, interest and meaning. Each factor is discussed in relation to literature on differentiated Instruction. Recommendations are made regarding the implementation of Differentiated Instruction to the STLS.

- Description: The play Miss Julie was published by playwright August Strindberg in 1888. It is a comment on the class issues in Sweden at the time (Leib, 2011). This commentary is achieved through telling the fictional tale of Julie, the daughter of a wealthy Swedish landowner, Jean, her father’s manservant, and Kristin, Jean’s betrothed who is also the house cook. During the course of a night and the next morning, Jean and Julie admit their feelings for one another, sleep together and plan to run away to start a hotel. In the morning, they ask Kristin to join them when they encounter her on her way to church. She refuses and vows to put an end to their plans. Seeing no way out, and fearing the wrath of Julie’s father, Jean hands Julie a razor and she walks outside, the inference being that she will commit suicide. The play Mies Julie is a South African adaptation, by South African playwright Yael Farber, of the August Strindberg play Miss Julie set in a farming kitchen in the Eastern Cape Karoo that premiered at the Grahamstown National Arts Festival in 2012. It has since been brought to London, the Edinburgh Festival and New York. Mies Julie presents a power struggle between Julie, the daughter of the white Afrikaans farm owner, and John, her father’s favourite farm worker and the son of Christine, the housekeeper who raised Julie. By altering Christine’s role from that in Strindberg’s play, where she was John’s (there Jean’s) fiancé, to that of John’s mother and Julie’s nursemaid, playwright Yael Farber has brought to the fore an interesting irony of South Africa’s history, which has been observed by Ena Jansen (2011) – white children who are raised, both during and post-apartheid, by black women who become part of the household of the privileged white families they work for.

- Description: The aim of this study was to investigate stakeholder participation and learning in the Seychelles Eco-School programme within a primary school context and a secondary school context. Findings from each Eco-School have been presented in two case studies with the goal to explore and describe how teachers, students, parents and organizations are participating and learning in the Eco-School programme. Six elements of school community were used to deepen understanding of the participatory and learning processes in each Eco-School, namely, leadership, management and administration, curriculum planning, teaching and learning, resource use and management, management of physical surrounds of the school and networks and partnerships. Some of the contextual variables in each Eco-School that were constraining and enabling stakeholder participation and learning in the programme have also been explored within this study. Data in this study was generated from historical documents analysed, semi-structured interviews, focus group discussions and field notes. Data was also generated from questionnaires completed by organizations involved in the programme at each Eco- School. Data was analysed in two phases, the first phase involved reading across data generated from the methods mentioned above to organize the data under broad themes in relation to the elements of school community. The second phase of analysis involved the use of the conceptual framework of situating learning in a community of practice to interpret and discuss the participatory and learning processes across the two cases. The study showed that in each Eco-School there is a community of practice with the active involvement of teachers and students and the occasional involvement of parents and organizations. Students and adults are learning as they engage together in classroom and field-work interactions, environmental projects, environmental activities to commemorate environmental theme days, environmental campaigns and co-curricular activities through the practices of each Eco-School community. It was also discovered that students and adults are making different contributions in the Eco-School community based on their level of participation in the programme. It is hoped that the findings in this research contribute information regarding community participation in environmental education programmes like the Seychelles Eco-School programme. In addition, findings will inform the Seychelles Government and its partners to consider the possibility of enhancing school and community partnerships to respond to some of the challenges of participation and learning in the Eco-School programme.

- Description: Since the Namibian independence in 1990, the education system has undergone some major revamping which involved the adoption of social constructivist perspectives in the teaching and learning of sciences. This learning theory acknowledges learners’ background prior knowledge as valuable tools in the effective construction of science concepts during lessons. A corollary is that the socio-cultural circumstances of learners might negatively influence the way learners construct new knowledge in the science classroom if they are not taken into consideration. This study was thus prompted by the need to understand how trainee science teachers engage with prior everyday knowledge and experiences, so as to enhance the conceptual development of biological concepts. The study was qualitative and it was underpinned by an interpretive paradigm with some elements of action research. Science trainee teachers at Katima Mulilo, Unam Campus were used as research participants. The techniques used to gather data included document analysis, brainstorming, observation, audio-visual, microteaching and semi-structured interviews. The results of this study showed that the changes that occurred during microteaching practices of the four trainee teachers involved in the study reflected their professional development in this approach. However, it emerged that prior everyday knowledge can be both a barrier and enabler to the construction of meaningful teaching and learning; hence its oversight may lead to instructional failures. The findings also indicated that selected platforms are essential to enable trainee teachers to incorporate prior everyday knowledge and experiences into the teaching of Western science. However, larger scale study should be conducted in order to deepen the understanding of the topic.

- Description: The last time a Formula One Grand Prix took place in South Africa was in 1993. In recent years, there has been a real interest in bringing the event to Cape Town and several proposals have been put forward to the City of Cape Town. Unfortunately, they have all been unsuccessful for various reasons, but mainly, because of the large financial costs involved. The cost involved to build all the infrastructure required for the event is usually reserved for developed, wealthy countries. Despite the positive role that a major event like this can have on the image of a city, there is resistance to invest money into a stadium or sporting infrastructure, which has the sole purpose of serving one big event like a Grand Prix. This treatise therefore focuses on the design of a multi-functional pit complex for a Formula One Grand Prix Street Circuit in Green Point, Cape Town. As an architectural example, which explores the potential of an adaptable approach to creating a long-term, economically sustainable piece of event infrastructure. The design includes all the necessary requirements for a facility of this nature including, a media centre, pit garages, race control centre and hospitality lounges, but adaptable, so as to function within the context of the Green Point area between annual Grand Prix events. The aim is to investigate the issues relating to Formula One Grand Prix as an event and the impact it has on a city. It will further endeavour to conduct a comprehensive study of the context of Green Point so as to gain an understanding of suitable, viable activities that will form part of the pit complex when the race is not in progress. Research into the creation of a structure formed by interchangeable building components and demountable connections are undertaken so as to promote the possibility for future transformation. As a result of this multi-functional, adaptable approach, the building is used all year round. This effectively reduces maintenance costs associated with infrequently-used buildings and allows for the sustainable use of the infrastructure, as a public asset, when the race is not in progress.

- Description: In the knowledge world into which mankind has progressed, universities are engines of economic growth. Their role has changed from producers of labour force to equal contributors - along with government and industry- in regional and national economic and social growth and development. Universities that will survive and succeed in this new climate must embrace entrepreneurship - become entrepreneurially oriented. As in any other organisation corporate entrepreneurship processes explain how entrepreneurship is implemented and diffused throughout a university, and its members must perceive the internal organisational culture as innovation supporting for entrepreneurship to flourish. Hence, the importance of studying internal environmental conditions that influence / enable corporate entrepreneurship. This study investigated NMMU’s entrepreneurial orientation by first determining what an entrepreneurial university is and its key attributes. Next it identified the key structural factors influencing university entrepreneurship and enquired how these structural factors can be influenced to enhance entrepreneurship at NMMU. To this end, survey method was used to sample perception of the university middle managers. The study first determined the level of entrepreneurship in NMMU by measuring its entrepreneurial intensity and then attempted to locate its position on the entrepreneurial grid. Next the level of the university’s internal environmental support for entrepreneurship was determined. The university’s culture was found to be the key factor influencing entrepreneurship with time availability and work discretion as key internal factors through which NMMU’s entrepreneurial culture could be improved. Proactivity and frequency dimensions of entrepreneurship were found to lead to significant improvement in the university’s entrepreneurial output and based on the outcome of the study; suggestions were made on ways of incorporating findings to better improve entrepreneurial orientation.

- Description: This research examined the legal nature of the presumption of guilt created by section 235(2) of the South African Tax Admiration Act and considered whether or not its practical application violates the taxpayer’s fundamental right contained in section 35(3) of the Constitution, which gives every accused taxpayer the right to a fair trial, including the right to be presumed innocent. The research also provided clarity on the constitutionality of this presumption because it has been widely criticised for unjustifiably violating the taxpayer's constitutional right to a fair trial. The conclusion reached is that the presumption created by section 235(2) of the Tax Administration Act constitutes an evidentiary burden rather than a reverse onus. It does not create the possibility of conviction, unlike a reverse onus where conviction is possible, despite the existence of a reasonable doubt. Therefore, it does not violate the accused taxpayer’s the right to a fair trial and the right to be presumed innocent and hence it is constitutional. Accordingly, the chances that the accused taxpayer will succeed in challenging the constitutionality of section 235(2) of the Act are slim.

- Description: This research examined the legal nature of the presumption of guilt created by section 235(2) of the South African Tax Admiration Act and considered whether or not its practical application violates the taxpayer’s fundamental right contained in section 35(3) of the Constitution, which gives every accused taxpayer the right to a fair trial, including the right to be presumed innocent. The research also provided clarity on the constitutionality of this presumption because it has been widely criticised for unjustifiably violating the taxpayer's constitutional right to a fair trial. The conclusion reached is that the presumption created by section 235(2) of the Tax Administration Act constitutes an evidentiary burden rather than a reverse onus. It does not create the possibility of conviction, unlike a reverse onus where conviction is possible, despite the existence of a reasonable doubt. Therefore, it does not violate the accused taxpayer’s the right to a fair trial and the right to be presumed innocent and hence it is constitutional. Accordingly, the chances that the accused taxpayer will succeed in challenging the constitutionality of section 235(2) of the Act are slim.

- Description: The Postmasburg Manganese Field (PMF), located in the Northern Cape Province of South Africa, once represented one of the largest sources of manganese ore worldwide. However, the discovery of the giant manganese deposits of the Kalahari Manganese Field (KMF) led to the gradual decline in manganese mining activity in the PMF. Two belts of manganese ore deposits have been distinguished in the PMF, namely the Western Belt of ferruginous manganese ores and the Eastern Belt of siliceous manganese ores. Prevailing models of ore formation in these two belts invoke karstification of manganese-rich dolomites and residual accumulation of manganese wad which later underwent diagenetic and low-grade metamorphic processes. For the most part, the role of hydrothermal processes in ore formation and metasomatic alteration is not addressed. The identification of an abundance of common and some rare Al-, Na-, K- and Ba-bearing minerals, particularly aegirine, albite, microcline, banalsite, sérandite-pectolite, paragonite and natrolite in the PMF ores studied in this thesis, is indicative of the influence of hydrothermal activity. Enrichments in Na, K and/or Ba in the ores are generally on a percentage level for the majority of samples analysed through bulk-rock techniques. The discovery of a Ba-Mn arsenate/vanadate similar to gamagarite may also indicate that the hydrothermal fluid affecting the ores was not only alkali-rich but also probably contained some As and V. The fluid was likely to be oxidized and alkaline in nature and is thought to have been a mature basinal brine. Various replacement textures, particularly of Na- and Krich minerals by Ba-bearing phases, suggest sequential deposition of gangue as well as oreminerals from the hydrothermal fluid, with Ba phases being deposited at a later stage. The stratigraphic variability of the studied ores and the deviation of their character from the pigeon-hole-type classification of ferruginous and siliceous ores in the literature, suggests that a re-evaluation of genetic models is warranted. The discovery of hydrothermallydeposited alkali-rich assemblages in the PMF and KMF provides grounding for further investigation into a possible regional-scale hydrothermal event at least re-constituting the ores. Some shortcomings in previous works include disregard for the highly variable nature of the PMF deposits, the effects of hydrothermal activity of the ores and the existence of stratigraphic discrepancies. This study provides a single, broad model for the development of all manganese deposits of the PMF. The source of metals is attributed to all formations that stratigraphically overly the Reivilo Formation of the Campbellrand Subgroup (including the Reivilo Formation itself). The main process by which metals are accumulated is attributed to karstification of the dolomites. The interaction of oxidized, alkaline brines with the ores is considered and the overlying Asbestos Hills Subgroup BIF is suggested as a potential source of alkali metals.

- Description: According to the latest Education Statistics Report published by the Department of Basic Education in March 2013, there were 12 680 829 learners and students in the basic education system in 2011, who attended 30 992 education institutions and were served by 441 128 educators. The vision of the Department of Basic Education is of a South Africa in which all our people have access to lifelong learning and education and training, which will, in turn, contribute towards improving the quality of life. Ultimately this will influence the building of a peaceful, prosperous and democratic South Africa. The emphasis is on excellence. Therefore maintaining high standards of performance and professionalism is a national imperative. However, this has not always been the case in terms of performance. For more than a decade we have witnessed dismal results in literacy and numeracy. This was accompanied by a low throughput rate. Despite the poor matric, literacy and numeracy results in South Africa as well as the low throughput rate, no teacher has been formally charged for poor performance in the last two decades. South Africa’s education budget is regarded as one of the highest in the developing world. Since 1993 the education budget has also grown substantially. South Africa’s education expenditure on education has grown from R30 billion in 1994/05 to R101 billion in 2007/08. Spending on education grew even further from R207 billion in 2012/13 to a projected R236 billion in 2014/15. Additional allocations of R18.8 billion over the medium term are accommodated, including equalisation of learner subsidies for no-fee schools and expanded access to grade R.6 Over the rest of the medium-term-expenditure framework (MTEF),7 spending on education, sport and culture will amount to R233 billion in 2013/14. The investment in education has not yet yielded the desired results and the outcome of education is not in keeping with the substantial input. This crisis in education is one of the major challenges facing Government, Administrators, educators, parents and children of today. According to Spaull,9 the South African government spends the equivalent of $1225 (R12440.26)10 per child on primary education, yet accomplishes less than the government of Kenya which spends only the equivalent of $258 (R2620.80)11 per child. Various reasons such as poverty, management, leadership, imbalances of the past, two unequal education systems, poor management, training and development, non-accountability, role of government and unions, have been identified for the poor state of our education system. However, what is noticeably absent and hardly mentioned in any of the position papers, is that not a single teacher has been held accountable and dismissed for incapacity for the poor performance in the education sector. Unfortunately, there is no record in any of the provincial education departments’ annual reports that a teacher has been dismissed or at least placed on a formal programme of incapacity for poor performance. Therefore, we have to ask the question: “Are we getting value for money?".

- 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.

A step forward in defining Hsp90s as potential drug targets for human parasitic diseases

- Description: Parasitic diseases remain a health burden affecting more than 500 million people worldwide with malaria having the highest mortality rate. The parasites can be transferred to the human bodies either through the mouth by ingestion of contaminated food and water or through the skin by bug bites or direct contact to environments harbouring them. Epidemiological control seems to be impossible since there is failure to control the insect vectors as well as practice of hygiene. Therefore, this has led to the development of a number of vaccines, chemotherapy and disease control programs. However, parasites have increasingly developed resistance to traditionally used anti-parasitic drugs and due to that fact there is need for alternative medication for parasitic diseases. Heat shock protein 90 (Hsp90) facilitates the folding of proteins in all living cells and their role is more important to parasites because of their environmental changes, from vector to host. Hsp90s play a major role; therefore this justifies the need for a deeper analysis of the parasitic Hsp90s. Recent studies have revealed that, the Plasmodium sp. Hsp90 has an extended linker region which increases the protein’s affinity for ATP and its inhibitors. Therefore we hypothesize that there are also significant features in other parasitic Hsp90s which would lead to Hsp90 being defined as potential drug targets. In the present study an attempt was made to gain more insight into the differences in primary structure of human and parasitic Hsp90s. The sequences were retrieved from the NCBI database and analysis was done in three groups basing on the localization of the Hsp90. The physicochemical properties were calculated and in every group, the protozoan Hsp90s showed significant differences when compared to the human orthologs. Multiple sequence alignments (MSA) showed that endoplasmic reticulum Hsp90s have an extended region in the middle domain indicating their ability to bind to a unique subset of client proteins. Sequence identities between the human and parasites showed that the protozoan Hsp90s are less related to the human Hsp90s as compared to the other parasites. Likewise, motif analysis showed the trypanosomatids and apicomplexan groups have their own unique set of motifs and they were grouped together in the phylogenetic analysis. Phylogenetic analysis also showed that, the protozoan Hsp90s forms their own clades in each group while the helminths did not form in endoplasmic reticulum group. In this study, we concluded that, Hsp90 can be a potential drug target for the protozoan species and more specifically those from the apicomplexan and trypanosomatids groups.

- Description: Various studies conclude that accelerated economic growth and development are necessary in South Africa to make a significant contribution towards reducing high levels of unemployment, inequality and poverty. Moreover, in theories of economic growth the export sector is frequently accorded a special role in encouraging faster economic growth, which is often supported by empirical evidence. Nonetheless, a question that remains unresolved is whether higher export growth leads to higher economic growth in South Africa and what particular role exports may play within the overall economic growth process of the country. This study applies Johansen’s cointegration procedure, impulse response functions, variance decomposition analysis and Granger causality tests to shed light on the channels through which export growth may impact South Africa’s economic growth rate. Quarterly time series data ranging from 1975q1 to 2012q4 is employed in the study’s empirical tests. The empirical results lend support to the idea that the role of exports in the economic growth process fundamentally lies in their ability to encourage investment and capital formation. While export growth supports higher economic growth in the short-run, it does not have the same effect in the long-run. Nonetheless, with export growth supporting faster capital formation in South Africa, and capital formation, in turn, significantly increasing economic growth in the long-run, the impetus to growth stemming from exports has been found to lie in the channel to capital formation. On the basis of the empirical results, not only are exports a critical requirement of higher investment, but they are also anticipated to play a prominent role in lifting the balance of payments constraint that would make investment-led growth possible in the first place. Overall, a strategy of export-led growth that does not explicitly emphasise the export-capital-growth connection is likely to fall short of reflecting the dynamics contained within the exports-growth relationship in South Africa.

- Description: Most land is still state owned and is granted to users through traditional authorities. Even though the government has undertaken some programmes to reduce rural poverty and has initiated land reform programmes, improved service delivery and formed new water rights legislation in rural areas, the problem of low crop production still persists among South African farmers. The study was undertaken to identify different farmers’ aspirations and goals for expanding their crop production from homestead gardening to irrigation plots in Mhlontlo Local Municipality, in the Eastern Cape of South Africa. The central problem is that smallholder farmers are not expanding their scale of crop production even though they have access to natural capital which includes land and water. The broad objective of the study was to determine the aspirations and goals of farmers to expand irrigation crop production from homestead gardens to irrigation plots. The specific objectives of the study were to assess factors that addressed smallholder farmers’ aspirations and goals to expand crop production, to identify challenges that smallholder farmers encountered in expanding from homestead gardens to irrigation plots and to determine the current state of homestead gardens and irrigation plots. A list of 20 goals were identified from the field survey with 54 homestead food gardeners and 50 smallholder irrigation farmers in the different villages of the Mhlontlo Local Municipality. Random sampling was used to select the farmers who were asked to score the identified farm enterprise goals in terms of their relative importance. The goals were categorised into five factors using Gasson goal ranking methods which ranked goals on the basis of intrinsic, expressive, instrumental, and social criteria. The next step was to determine the standard deviations and means of the ranked goals. Descriptive statistics was then used to profile the farmers according to such factors as age, gender, years of farm experience, types of plot, the availability of water and land for crop production, the income farmers generate from the sale of crops produced and these are cross-tabulated with their goal rankings. The Logit model was used to estimate the probability that farmers would belong to a particular goal ranking and performance category. The logit model was also used to identify the factors that influence the expansion of the cropped area. The results revealed that maize production and land size where significant at 1%. Age and type of irrigation used were also positively significant at 1%. The results also revealed that the adoption of agricultural technology by smallholder irrigation farmers and homestead food gardens contributed to better quality produce.

The Logit model was used to estimate the probability that farmers would belong to a particular goal ranking and performance category. The logit model was also used to identify the factors that influence the expansion of the cropped area. The results revealed that maize production and land size where significant at 1%. Age and type of irrigation used were also positively significant at 1%. The results also revealed that the adoption of agricultural technology by smallholder irrigation farmers and homestead food gardens contributed to better quality produce.

- Description: Mealybugs (Planococcus citri) and thrips (Scirtothrips aurantii) are common and extremely damaging citrus crop pests which have proven difficult to control via conventional methods, such as chemical pesticides and insect growth regulators. The objective of this study was to determine the efficacy of entomopathogenic fungi against these pests in laboratory bioassays. Isolates of Metarhizium anisopliae and Beauveria bassiana from citrus orchards in the Eastern Cape, South Africa were maintained on Sabouraud Dextrose 4% Agar supplemented with Dodine, chloramphenicol and rifampicin at 25°C. Infectivity of the fungal isolates was initially assessed using 5th instar false codling moth, Thaumatotibia leucotreta, larvae. Mealybug bioassays were performed in 24 well plates using 1 x 107 ml-1 conidial suspensions and kept at 26°C for 5 days with a photoperiod of 12 L:12 D. A Beauveria commercial product and an un-inoculated control were also screened for comparison. Isolates GAR 17 B3 (B. bassiana) and FCM AR 23 B3 (M. anisopliae) both resulted in 67.5% mealybug crawler mortality and GB AR 23 13 3 (B. bassiana) resulted in 64% crawler mortality. These 3 isolates were further tested in dose-dependent assays. Probit analyses were conducted on the dose-dependent assays data using PROBAN to determine LC₅₀ values. For both the mealybug adult and crawlers FCM AR 23 B3 required the lowest concentration to achieve LC₅₀ at 4.96 x 10⁶ conidia ml-1 and 5.29 x 10⁵ conidia ml-1, respectively. Bioassays on adult thrips were conducted in munger cells with leaf buds inoculated with the conidial suspensions. Isolate GAR 17 B3 had the highest mortality rate at 70% on thrips while FCM AR 23 B3 resulted in 60% mortality. Identification of the isolates, FCM AR 23 B3, GAR 17 B3 and GB AR 23 13 3, were confirmed to be correct using both microscopic and molecularly techniques. ITS sequences were compared to other sequences from GenBank and confirmed phylogenetically using MEGA6. Mealybug infection was investigated using scanning electron microscopy, mycosis was confirmed but the infection process could not be followed due to the extensive waxy cuticle. These results indicate that there is potential for the isolates FCM AR 23 B3 and GAR 17 B3 to be developed as biological control agents for the control of citrus mealybug and thrips. Further research would be required to determine their ability to perform under field conditions.

- Description: This study aimed to investigate the effects that a specifically tailored goal-setting program would have on two motocross racers in terms of their self-efficacy and motivation, as well as the process of designing this intervention. This case-study approach involved a mixed methods approach, consisting of pre-intervention and post-intervention assessments, interviews, and performance profiles. The tools used include Vealey’s (1986) Competitive Orientation Inventory (COI), Gill and Deeter’s (1988) Sport Orientation Questionnaire (SOQ), performance profiles, and semi-structured interviews. The goal-setting intervention lasted a total of five weeks. The results from the preintervention and post-intervention assessments were compared to determine whether any changes in motivation or self-efficacy occurred during the intervention. For the first participant, significant changes in both motivation and self-efficacy were present in addition to significant changes in competitive orientation. For the second participant, there were no significant changes in either motivation or self-efficacy. However, for the second participant there was also no change in competitive orientation. Findings suggest that the focus and competitive orientation of an athlete have a significant influence on the types of goals set, and consequently on positive changes in motivation, confidence, and self-efficacy. The influence of the competitive orientation in athletes also highlighted the importance of attaining a balance between performance and outcome goal-related activities. It was also discovered through qualitative assessment that this program is suitable for particular groups of athletes such as those who are injured, display an external locus of causality or are otherwise not performing at their prime.

- Description: This thesis focuses on the labour process within the minibus taxi industry in East London, South Africa. This industry is structurally situated within the informal sector or economy but is marked by contradictory processes of formalisation and in-formalisation. Though the taxi industry seems to straddle the formal and informal economies in South Africa, the study is conceptually framed in terms of the informal sector but in a critically-engaged fashion. The very distinction between formal and informal economies, whether in South Africa or elsewhere, is open to dispute; and, even if accepted, there are differing conceptualisations of the relationship between the ‘two’ economies. Also, the conceptual clarity of the term ‘informal economy’ has been subject to scrutiny, given the vast range of activities it is said to incorporate. While the distinction between formal and informal economies may be a useful conceptual starting-point, this thesis demonstrates that it is analytically useful to speak of degrees and forms of formalisation and in-formalisation along a continuum, rather than to dichotomize economies. The thesis therefore analyses in depth the competing and tension-riddled processes of formalisation and in-formalisation in the minibus taxi industry, and with a specific focus on the labour process.

- Description: The 1996 Constitution provides workers with the right to form and join trade unions and to participate in the activities and programmes of those trade unions. The organizational and associated rights contained in sections 23(2)-(4) of the Constitution of Republic of South Africa, form the bedrock of a labour-relations system characterized by voluntarist collective bargaining. The constitutional protection that the above section gives to these organisational rights shields the trade unions and employer organisations from legislative and executive interference in their affairs and in turn, inhibits victimisation of and interference in trade unions by employers. One of the expressly stated purposes of the Labour Relations Act of 1995 (hereinafter referred to as the “LRA”) is to promote collective bargaining and to provide a framework within which employers, employers’ organisations, trade unions and employees can bargain collectively to determine wages, terms and conditions of employment, other matters of mutual interest and to formulate industrial policy. Notwithstanding the above purpose, the Act does not compel collective bargaining, with the result that the courts have no role in determining, for example, whether an employer should bargain collectively with a trade, what they should bargain about, at what level they should bargain or how parties to a negotiation should conduct themselves. Despite this, by extending and bolstering the right to strike, the LRA has effectively empowered trade unions to have recourse to the strike as an integral aspect of the collective bargaining process. The LRA provides a framework that is conducive to collective bargaining and thus providing for the establishment of bargaining councils. The purpose of this treatise is to examine the role played by the Education Labour Relations Council (hereinafter referred to as the “ELRC”) as one of the sectoral bargaining councils in the Public Service, in collective bargaining. In order to place this discussion in context, it is valuable to know the history of industrial relations and collective bargaining in South Africa.

- Description: Inclusive education and the abolishment of corporal punishment by the National Department of Education have a profound influence on the behaviour of the learners in the classroom. Behaviour displayed by learners challenges the authority of educators and stand in direct contrast to a peaceful classroom setting which is a key element of the learning process. Educators found themselves at a loss, not knowing how to retain order and discipline while valuable teaching time is lost. The aim of this study is to identify and determine how educators can be empowered to deal with challenging behaviour in their high school classrooms. A qualitative study was conducted for this purpose, in four high schools which is situated in the Northern Areas of Port Elizabeth in the Eastern Cape. To obtain the necessary data different data-collection techniques were used, namely questionnaires and interviews. Learners, educators and parents were participants in the study. The findings suggested that most educators do not have the skills and/or knowledge to cope with challenging behaviour displayed by learners in the classroom. Conditions where educators are unable to control the behaviour of learners undoubtedly leads to the degradation of teaching and learning, so the need to address the problem was real. The concluding chapter recommends strategies of dealing with challenging behaviour through classroom management, educator skills as well as disciplinary strategies. An environment that is conducive for teaching and learning will be created by such strategies.

- Description: As the number of computing devices connected to the Internet increases and the Internet itself becomes more pervasive, so does the opportunity for criminals to use these devices in cybercrimes. Supporting the increase in cybercrime is the growth and maturity of the digital underground economy with strong links to its more visible and physical counterpart. The digital underground economy provides software and related services to equip the entrepreneurial cybercriminal with the appropriate skills and required tools. Financial malware, particularly the capability for injection of code into web browsers, has become one of the more profitable cybercrime tool sets due to its versatility and adaptability when targeting clients of institutions with an online presence, both in and outside of the financial industry. There are numerous families of financial malware available for use, with perhaps the most prevalent being Zeus and SpyEye. Criminals create (or purchase) and grow botnets of computing devices infected with financial malware that has been configured to attack clients of certain websites. In the research data set there are 483 configuration files containing approximately 40 000 webinjects that were captured from various financial malware botnets between October 2010 and June 2012. They were processed and analysed to determine the methods used by criminals to defraud either the user of the computing device, or the institution of which the user is a client. The configuration files contain the injection code that is executed in the web browser to create a surrogate interface, which is then used by the criminal to interact with the user and institution in order to commit fraud. Demographics on the captured data set are presented and case studies are documented based on the various methods used to defraud and bypass financial security controls across multiple industries. The case studies cover techniques used in social engineering, bypassing security controls and automated transfers.
