- Description: Chronic non-communicable diseses are a global public health challenge that continuously threatens the development and health of humans. Risk factors such as unbalanced diet-the high consumption of processed food or food from animal origin are responsible for NCDs. NCDs result in weakened immune system, making the host susceptible to opportunistic infections. Thus, the NCDs burden is most times chronic and multiple with the illness and suffering of the affected person numerous. The lack of cure for NCDs, the high cost of drugs, their high side-effects, and the emergence of multiple drug resistance has given rise to the investigation of other sources for therapeutic cure such as medicinal plants. The ethanol, n-hexane and ethyl acetate extracts of Olea europaea were analysed for their antioxidant and antimicrobial activities. The essential oil was also analysed for their chemical constituents. The n-hexane extracts of O. europaea exhibited no inhibition against all of the microorganisms tested, while the ethyl acetate and ethanol extracts exhibited inhibition, with minimum inhibitory concentration values between 0.625 mg/ml to 1.25 mg/ml. The ethanol leaf and ethyl acetate stem extracts exhibited significant activity in the inhibition of 2, 2-azinobis-(3-ethylbenzothiazolin - 6-sulfonic acid diammonium salt (ABTS) free radical, the n-hexane leaf extract had the overall significant lipid peroxidation inhibition activity, while in the inhibition of 2, 2- diphenyl-1-picrylhydrazyl radical (DPPH), the ethanol and ethyl acetate leaf extracts had strong activity. Nonanal, phytol, α-Pinene, α-Phellandrene, spatulenol and farnesol were some of chemical components identified after the GC-MS analysis of O. europaea oil. In the final part of the dissertation, Euryops brevipapposus essential oil was assessed for the antioxidant activities using free radical scavenging assays. In addition to this, the antimicrobial activities were assessed and the chemical composition was analysed using GC-MS. The essential oil demonstrated significant antioxidant activity against 2, 2-diphenyl-2-picryl-hydrazyl free radical (DPPH), 2, 2′-azino-bis (3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) and lipid peroxides with IC50 value of 0.0000000671 mg/ml, 1.05 mg/ml, and 1.170 mg/ml respectively. The essential oil also showed significant activity against all microorganisms tested with minimum inhibitory concentration (MIC) values between 0.055 mg/ml to 0.5 mg/ml. α-pinene, α- Phellandrene, germacrene D, β-pinene, trans- β.-Ocimene, bicyclogermacrene and β -Phellandrene were some of the chemical compounds identified in E. brevipapposus oil. The study has shown that E. brevipapposus and O. europaea are abundant in phytochemical compounds which were thought to be the root cause for the activities demonstrated. Therefore, these therapeutic properties observed validate and elucidate the traditional usage of the both plants in the treatment /management of diseases.

- Description: Central to the sustainable and competitive growth of the South African construction industry is a predictable cash flow through on time payment by clients to contractors. However, chronic late payments, a recurring problem in the industry, especially in the public sector, is bringing untold hardship to contractors by derailing their competitiveness and also eroding the trust among the supply chain partners to the extent that some firms end up closing business in the industry. The situation is viewed from the lean construction perspective as an obstacle that is preventing the accrual of the required value to project parties in the construction industry. This research addresses the causes of late payments to contractors and the role of the quantity surveyor (QS) in terms of influencing early payment from a lean construction perspective. A mixed method approach was used for compiling the primary data for the study. Sequentially, one hundred and two (102) quantitative and twelve (12) interview questionnaires were administered to selected contractors and construction professionals working predominantly on public sector projects. The findings revealed that the approval process for evaluation and certification by the client- appointed agent and intermediary institutions is taking longer than contractually allowed, with parties independently undertaking their evaluation prior to the certification date. This is found to be adverse to achieving consensus on the values of the works for authorisation. Other significant barriers are the lack of funds to authorise payment, random auditor general’s documentation changes, lack of administrators’ system integration and capacity to handle cyclical payment processing. Also, contractors have been found to be in default of timeously submitting complete claim documents. It is therefore recommended that the client agents should partner with the contractor in regular design and documentation reviews, arranging the payment process and should also meet jointly to prepare monthly evaluations. In addition, contractors should be mentored from the onset of the project regarding all the necessary documentation and supporting documents that will be required by the client to ensure that payment approvals are not delayed. The payment authori-sation agent’s capacity should be enhanced through training and improved powers as a singular point of control to perform efficiently and their systems and processes should be integrated to ensure that all parties are implementing the same protocols.

- Description: I embarked upon this study to investigate mathematics teachers' practices that have led to the persistence of traditional teaching methods in grade 9 mathematics classrooms in Rundu. The study was conducted from a learner-centred (L-C) perspective or reform approach in the Namibian context. It is a qualitative study oriented in the interpretive paradigm- a paradigm that seeks to understand the meanings attached to human actions. The participants involved in this study were purposively selected and they are composed of two mathematics teachers and their grade 9 learners. This study was conducted at two schools in Rundu. One is an urban school while the other one is a rural school on the outskirts of Rundu. The research tools employed in this study are questionnaires, interviews and observations. The questionnaires were used to identify and select my participants while the observations were used to investigate the participants teaching strategies. The purpose of the interviews was mainly to investigate teachers' understanding, interpretation and implementation of learner-centre education (LCE). Amongst other findings, this study reveals that inadequate teacher-training, controversial educational policies and challenges such as overcrowdedness in mathematics classrooms, lack of teaching and learning materials, lack of cooperation among mathematics teachers and learners' negative attitude towards mathematics are some of the contributing factors to the persistence of traditional teaching methods in mathematics classrooms. Moreover, the study reveals that the persistence of traditional teaching methods in mathematics classes can no longer be attributed to the lack of understanding of LCE. The teachers in this study seem to be well acquainted with the theoretical aspect of the LCE framework while the implementation aspect seems to be a concern.

- Description: LH gonadotropes are successfully identified in the anterior pituitary of Minioptems schreibersii and Rhinolophus capensis, using immunogold labelling at the light and electron microscopy level. The gonadotropes are oval to polygonal in shape and possess numerous small secretory granules, which contain LH throughout the year. Their distribution is similar in both species, although the abundance varies slightly between species and sexes. Seasonal changes are detected in gonadotrope ultrastructure, pituitary LH levels, and plasma hormone levels, and activity pattern of LH gonadotropes generally coincide with reproductive activity in both bat species. In female M. schreibersii gonadotrope activity, pituitary LH, and plasma LH levels coincide with development, implantation and gestation. During the delayed implantation gonadotropes are inactive and and high follicular period of plasma LH levels are low, coinciding with corpus luteum inactivity and low plasma progesterone levels. Implantation coincides with increased activity of the gonadotrope activity, increased plasma LH levels, reactivation of the corpus luteum and elevated plasma progesterone levels. Activation of LH gonadotropes towards the end of hibernation may be initiated by the winter solstice, which marks the change to increasing daylength. In female R capensis gonadotrope activity and high pituitary and plasma LH levels occur towards the end of follicular development. During hibernation gonadotrope activity and plasma LH levels decrease. Ovulation coincides with increasing gonadotrope activity (which follows the winter solstice), although a preovulatory peak in plasma LH is not detected. In male M. schreibersii and R. capensis, gonadotrope activity and high plasma LH and testosterone levels coincide with spermatogenesis, except during a period of reproductive inactivity in spring in male M. schreibersii, where gonadotropes appear active and plasma LH and testosterone levels are high. The reason for this apparent activity is not known. Male sperm storage during hibernation in male R. capensis coincides with low gonadotrope activity and low plasma LH and testosterone levels. Factors initiating gonadotrope activity and hence spermatogenesis are probably decreasing daylength (summer solstice) in M. schreibersii and increasing ambient temperatures and food abundance (following the hibernation period) in R.capensis.

- Description: A description of the geochemistry of tungsten is given. The geochemical properties of tungsten have a strong influence on its mineralogy, distribution and abundance in crustal rocks and rock-forming minerals , and its migration/deposition within the ore-forming and supergene environments. The behaviour of tungsten during migration, from source to site of deposition, within the crust is discussed in some detail and environments considered favourable to the concentration of tungsten ore minerals are suggested. All major types of tungsten ore deposit are described with emphasis placed on those of greater economic importance. Characteristic features of each type of deposit are particularly emphasized in order to provide clear guidelines to exploration. Hydrothermal, pyrometasomatic and stratabound tungsten deposits present themselves, economically, as the most important exploration targets. The recently developed concept of syngenetic stratabound tungsten mineralisation is outlined. Exploration for deposits of this type should be aimed predominantly, but not exclusively, at volcano-sedimentary sequences of Lower Palaeozoic age, particularly within regions known to contain occurrences of Sb and Hg. Tungsten deposits commonly contain concentrations of one or more of the following metals: Sn, Sb, Bi, Mo, Au and Ag. The presence and possible extractive value of these metals, together with commonly associated metal impurities such as As, must always be taken into account in a feasibility study , Adobe Acrobat 9.53 Paper Capture Plug-in

- Description: Since its inception, consumption behaviour theory has developed to account for the important social aspect that underpins or at least to some extent can be used to explain consumption behaviour. Modern consumption behaviour theory is anthropocentric in nature, with people and societal influence at the forefront of the theory. To date, empirical studies on consumption behaviour of cultural activities (for example, music and arts), entertainment and sport have used Bourdieu’s (1984) omnivore/univore theory to suggest that consumption of leisure activities is bound up in social ties. To date, no such investigation has been conducted in the context of sport in South Africa. The aim of the study therefore is to investigate whether South African cricket spectators are sporting omnivores or univores, thus, essentially investigating whether sports consumption behaviour in South Africa is bound up in social ties. A number of positive economic and social ramifications could result from gaining a holistic understanding of sports consumption behaviour in South Africa. Given these ramifications, the secondary goal of the research is to identify motives for consumers making specific sport consumption decisions, and determining whether certain characteristics can be attributed to these consumption decisions. Recommendations based on the findings of the research could help various stakeholders understand sports consumption patterns in South Africa, which could in turn lead to the realization of positive economic and social benefits. The study made use of a questionnaire, administered at four different limited overs cricket matches in the 2012/13 cricket season, to obtain a range of responses reflecting specific types of consumption behaviour as well as motives for consumption decisions of cricket spectators in the Eastern Cape. Using individual binary probit models and post estimation F-tests, the results indicate that consumption behaviour of sport within South Africa predominantly differs on the grounds of education and race. This suggests that there are aspects of social connotations underpinning sports consumption behaviour within South Africa

- Description: This dissertation examines Elias Canetti‟s novel, Auto-da Fé, in an attempt to show how it depicts the manifestations of violence and the effects of traumaon the individual and on modernist society. This analysis of Auto-da Fé concentrates on the representation of trauma on a fictional level at a time when Europe was experiencing political, social and economic upheaval after the First World War. Auto-da Fé provides an intense emphasis on the psychological effects of trauma on the characters; thereby reflecting the turmoil of this period. An analysis of Canetti‟s novel, in the light of trauma, reveals an enigmatic testimony not only to the nature of violent events, but of the way trauma resists simple comprehension. I argue that this gives rise to complexities within the narration by tracing the insistently recurring words and symbols which point to an interpretation beyond the thematic content of the text, namely one which repetitively bears witness to hidden wounds within individual consciousness. The titles of the three parts of Auto-da-Fé reflect a condition of somatic and sychosomatic dislocation: “A Head without a World”, “Headless World”, and “The World in the Head”. My argument is that the fictional trauma in Canetti‟s novel contains several characters who suffer from a breach of the self and the inability to comprehend society. The inability to fit into society results in the protagonist creating an isolated refuge in order to protect himself from the outer world. However, his alienation exacerbates his physical and emotional dislocations and ultimately leads to his destruction.

- Description: South Africa is characterised by high levels of HIV infections and unwanted pregnancies, despite the vast amount of interventions aimed at combatting this issue. It becomes important to explore why these interventions are not actively achieving what they aim to. A major cause for concern is the increase in risky sexual behaviour in the adolescence and young adult (15-24 year) age group. In various cultures, women’s socialization has a direct impact on their ability to prioritize their sexual health. Steeped in patriarchal ideology, many South African cultures prioritise the power of masculinity over and above the femxle experience. Improved partner communication leads to decreased risky sexual behaviour, but it becomes tricky when the relationship is characterized by a gender power imbalance. This study is aimed at understanding South African femxle sexual health by focussing on 1) the extent to which the overarching traditional beliefs about femininity is related to their sexual self-efficacy. Furthermore, it is aimed at 2) the extent to which they engage in sexual activity and behaviour that would protect them from STIs and unwanted pregnancies. Research design is quantitative and include an online survey for femxle students between the ages of 18 and 24, enrolled at the Nelson Mandela University, South Africa. The data was analysed statistically, where after the research findings will be interpreted from the perspective of Feminist Psychological Theory.

- Description: Despite more than a century of introductions, fish invasions are poorly understood in South Africa. This thesis aims to: (1) provide baseline information on the fish fauna in five inland water bodies (four dams: Theewaterskloof, Clanwilliam, Quaggaskloof, and Voelvlei and a natural lake, Groenvlei) in the Western Cape; (2) determine which species were established and provide a baseline of abundance and size structure for monitoring and, (3) make preliminary recommendations for a fishery. First, criteria for determining establishment were developed by undertaking a full biological assessment of bluegill Lepomis macrochirus, a data-poor species in South Africa. This included the assessment of growth rate using validated estimates of age derived from otoliths in two dams (Clanwilliam Dam: Lt=335.9(1−eo.113(t+1.06)); Groenvlei: Lt=287.2(1-e−0.171(t+0.54)). Length at 50% maturity was similar for males (146 mmFL) and females (147 mmFL). Length frequency analysis combined with data on the age and growth and reproduction demonstrated that established populations of bluegill contained several age cohorts as well as mature and juvenile fishes. A meta-analysis was conducted to: (1) compile a list of initial stocking dates for all alien fishes in each waterbody and (2) use angler tournament data to assess for additional species and persistence over time. Data from the meta-analysis was combined with ichthyological survey data to determine establishment success. These data demonstrated that nine non-native species had established in the five water bodies. Clanwilliam Dam had the largest number (7) of non-native species established, Groenvlei (5) and Theewaterskloof, Brandvlei and Voelvlei the lowest with four species. The state of invasion of each species in the province showed that all nine species are categorised as invasive. This information on establishment was then integrated into a framework for rapidly determining what type of fishery would be most suitable for the 5 waterbodies. Potential yield was estimated using morphoedaphic models, were 260 t/yr for Theewaterskloof Dam, 93 t/yr for Voelvlei, 81 t/yr for Brandvlei, 59 t/yr for Groenvlei and 55 t/yr for Groenvlei. The CPUE for Groenvlei was the highest in gill nets with 1.32 ± 1.94 kg/h, then Voelvlei 1.05 ± 1.34 kg/h followed by Brandvlei (0.84 ± 1.48 kg/h), Clanwilliam (0.71 ± 1.55 kg/h) and lastly Theewaterskloof (0.36 ± 0.41 kg/h). Only Theewaterskloof could produce in excess of 100 t/yr but less than 400 t/yr of fish making it suitable for a small scale fishery. The CPUE values of Theewaterskloof were the lowest and a gill net fishery on this water body may not produce sufficient fish for the fishery. All water bodies had a high recreational angling usage, the opening of a small scale fishery could be detrimental to this industry. Subsistence and recreational anglers should be promoted with the possibility of a long line industry targeting Clarias gariepinus.

- Description: Until recently most sandy beach studies have made use of snapshot samples but the validity of this approach has been widely questioned. In this study we attempt to resolve this issue by repeatedly sampling two beaches using a stratified random design. Three sampling sessions took place, each approximately six months apart. The three sites on the first beach were selected according to the type of beach (reflective, intermediate and dissipative) with each morphological type duplicated on the second beach. Many of the physical variables measured had significant differences between the sampling sessions but only a few were significantly different between the Sites. Very few of the individual physical variables had significant relationships with the sandy beach macrofaunal abundance and density. However, composite indices had a greater number of significant relationships with the macrofaunal abundance and density. Also very few significant relationships were seen between the species richness and the physical variables of the beaches studied. Effluent line crossing frequency was the only physical variable that could predict species richness but it was considered a weak predictor. Changes in the zonation patterns within and between beaches were also investigated. The highest concentration of taxa and individuals was found near the low-water mark with a gradual reduction of both towards the high-water mark. Some of the sandy beach community variables (abundance, density and species richness) showed significant difference between the sampling sessions but no significant differences were seen between the two beaches. The presence of three zones was noted using MDS plots and Cluster diagrams. However, using a SIMPER analyses, four zones with the possibility of a fifth was noted.

- Description: This study is a contribution to the ongoing debate concerning the role and involvement of foreign donor entities in the processes of transforming and creating viable and sustainable municipal entities in South Africa. The discussion particularly focuses on the relationship between the donor community and the Department of Provincial and Local Government (DPLG) and how this relationship has been nurtured, coordinated and managed. The study acknowledges the challenges pertaining to local government transformation and the role and mandate assigned to the DPLG by the South African Constitution and the Presidential Coordinating Council (PCC) for it to facilitate the creation of developmental local government. In discussing this, consideration is given to capacity and resource constraints within the Department, which necessitate that it collaborates closely with other stakeholders, particularly donors, in seeking to augment its resource base and capacity. The Department's lack of capacity is further complicated by the various pieces of legislation, which have a serious bearing on how municipalities have to work - irrespective of their capacity and resources limitations. The research also focuses on how this relationship, between the DPLG and foreign aid donors working in the local government sector, is coordinated and managed. From evidence gathered and interviews conducted, the conclusion is drawn that there is much room for the DPLG to improve and strategically focus its interaction with donors as informed by its mandate and strategic priorities. Proposals, which entail development of donor management guidelines, setting up of a donor coordination unit within DPLG, the improvement of the understanding of donor work politics and modalities among DPLG officials, etc., are made.

- Description: This mini thesis proposes that the Dance Factory in Ne'Ntown, Johannesburg, is a site of resistance. Its source and motivation are the personal, artistic and socio-poIiticaI sites ofresistance to mainstream forms of dance with nationalistic tendencies and to dominant ideological hegemonies that enforced apartheid or nationalism. Therefore, these sites or resistance are examined prior to and after the democratisation of South African culture. An analysis of the dances choreographed in this period of transition and changing hegemonies reveal shifts of resistance. These are traced within the development of the Dance Factory. Chapter one explores the notion of resistance as a form of power and the notion of site, where the operations of power evoke resistance. Three sites of resistance within South African dance culture are identified and examined. These are the Dance Factory, the artistic site of dance and the site of the dancing body. The chapter reveals the development of these sites in a changed culture and notes a re-orientation of resistance within dance, namely Afro-fusion, and the subsequent development and emergence of 'alternative' sites of resistance. These reveal new expressionistic tendencies, body politics and the feminist strategies of 'new poetics' and 'ecriture feminine'. The codified mainstream forms of dance, subject to nationalistic strategies of dassicism and its inherent Iogocentricity are challenged and destabilised by the emergence of these altemative resistant forms of dance. Chapter two examines the artistic policies of the Nationalist Govemment, the African National Congress and the Dance Factory from 1983-1997. It notes the effects of the changes in the artistic policies on sites of resistance in dance, performed at the Dance Factory. The chapter desaibes the development of the Dance Factory, its policies of diversification as a strategy of resistance, its promotion of praxis, its resistance to nationalism and the ramifications thereof. It also explores the effects of a governmentalisation of culture and the role of the organic intellectual within the Dance Factory. An analysis of the alternative dance work 'Torso-Tongue" in chapter three furthers the argument that the Dance Factory maintains and encourages the changing sites of resistance in dance. This analysis demonstrates the resistant aspects of dance as discussed in chapter one and thereby confirms the aims and missions of the Dance Factory. The thesis examines the role of the Dance Factory as it develops, nurtures and responds to the shifts in resistance and changes in culture and dance. Most importantly the thesis exposes the resistance to and the effects of an imposition of a nationalistic ideology on dance. The resultant resistance to this form of domination is explored in dance within the site of the Dance Factory, thus supporting the premise that the Dance Factory is a site of resistance.

- Description: The aim of this qualitative research study is to develop insights into the dynamics involved in work- family conflict, balance and coping strategies. The study explores the experiences of seven professional women, who are also mothers, employed in professional work positions in Grahamstown. The research is interpretive in nature as it aims to explore the conflicts experienced by the professional mothers in balancing their competing roles. The study focused on the demands that these women face and the coping strategies that these working mothers develop and use, in order to balance their career aspirations as well as their family responsibilities. It set out to explore the women’s perceptions of work- family conflict and the extent to which they experience it, further examining the compromises that the women have had to make and possible feelings of guilt or regret that they may have experienced. The findings indicated that this balance is sensitive to many facilitating and hindering factors. The participants revealed that they experience work- family conflict, and that the experience of it has largely to do with the guilt of not spending enough time with their family. Another significant finding was that the women expressed their coping strategies as being organised; forming a line between work and family life as well as employing domestic workers. The women further stated that there are constant compromises that have to be made to fit in the multiple roles, and that feelings of guilt and/or regret do set in at times.

- Description: Within the context of debates concerning the impact of media on audiences, this study takes the form of a qualitative audience reception analysis; to investigate how a particular group of female audiences situated in Zimbabwe interprets televised HIV/AIDS prevention advertisements. It examines the extent to which the social context influences the audiences’ acceptance or rejection of preferred readings encoded in the texts. The study is situated within the broad theoretical and methodological framework of both the communication for development and the cultural studies approaches to the study of the media. Data for the investigation was collected through the focus group and in-depth interview methods as well as through the websites and organisational documents produced by the encoders of the advertisements. The findings indicate that the female audiences’ interpretative strategies were informed by their lived experience as well as pre-existing knowledge. Based on the findings it can be deduced that, contrary to earlier beliefs and media theories such as that of the “hypodermic needle” theory the audience of public communication is not a passive homogenous mass that easily succumbs to media influences, rather the audience is active in the production of meaning, but under determinate conditions in particular contexts. The texts, the producing institutions and the social history of the audiences supply these conditions.

Methods: The study involved 305 school children (159 boys and 146 girls) randomly selected from primary schools in Alice sub-district, Nkonkobe Municipality. Body weight, height, skinfold thickness and girth measurements were measured using standard procedures. Overweight and obesity were defined using body mass index (BMI) for age and gender. Derived variables were: fat mass, fat-free mass, fat mass index, fat-free mass index, waist-to-hip ratio, waist-to-height ratio and subscapular-to-triceps ratio. Motor development levels were measured and assessed using Test of Gross Motor Development –Second Edition (TGMD-2). Blood pressure was measured using aneroid sphygmomanometer. Results: Boys had higher mean values of blood pressure (69.19 ± 7.30 and 38.15 ± 5.91) compared to girls (68.39 ± 7.97 and 37.11 ± 7.53). The proportion of overweight among girls (15.75 percent) was higher compared to boys (10.69 percent). Likewise, the percentage of obesity among boys (16.35 percent) was higher compared to girls (10.27 percent). The motor development results showed that girls (40.9 ± 6.54) performed better than boys (39.7 ± 6.64) in locomotor skills test. Conversely, boys (39.8 ± 7.62) performed better than girls (38.6 ± 7.29) in object control. Conclusion: The prevalence of overweight and obesity among the children is alarmingly high and concerning for the health. At all ages, girls had higher body fat percentage and fat mass than the boys. However, FFMI and WHR were higher in boys compared to the girls. There is no gender difference in the waist-to-height ratio and STR of both boys and girls. The locomotor raw score is higher in girls than in boys; however, the object control raw score is higher in boys compared to girls. The non-correlation of BMI with TGMD-2 tests suggests an equal potential of motor development among the children, regardless of their body fatness. There is need for obesity prevention programme in schools, which should involve all the stakeholders (teachers, parents/guardians, government, NGOs). The programme should focus on creating awareness concerning child body weight, healthy dietary intake and regular BMI screening in schools.

- Description: In the past the emphasis was given to intelligence as the 'sole major determining factor where academic success was concerned and Warburton (1969) wrote: The ignorance of educationists in the field of personality makes a striking contrast to their ability to estimate educational and intellectual capacity, imperfect as that may be. The understanding of children's personality and the teacher's ability to assess these traits is perhaps the most important topic in the whole field of education'. Where would we be today if we assumed that all children are of equal intelligence? We cannot therefore assume they are equally anxious, introverted and have the same persistence in the performing of a task, just as we cannot assume they have equal intellectual capabilities. " ... Any attempt to understand the complete causal chain associated with school attainment must include the effect of personality on the child's work in the school." (Eysenck , 1972). Intro. p. 1.

- Description: This study examined the nature of learning within an afterschool mathematics club established by the South African Numeracy Chair project. The study sought to establish what sort of progress in mathematical learning occurred in a grade 3 afterschool maths club, using assessment instruments associated with the Learning Framework in Number. The study also sought to understand the nature and effects of mentor mediation in the maths club, using Vygotsky’s notion of the Zone of Proximal Development (ZPD) together with the notion and practice of scaffolding. The study made use of a variety of data collection techniques, including one-to-one assessment interviews, task-based interviews and observations. In line with the case study approach adopted, four learners were selected for interviews. The assessment interview results revealed that, in terms of proficiency in early arithmetical learning, all four learners showed progress after spending four months in an afterschool maths club. Even though they were found to have advanced in their Strategies for Early Arithmetic Learning (SEAL), some of them were observed still using their fingers to support their counting. Such strategies were likely to mirror the teaching approaches used in their usual school mathematical lessons. The overall findings in terms of learners’ proficiency and progress give rise to concerns about current number teaching practices in their school, which emphasize the standard written algorithm in the lower primary grades. The study also made use of Vygotsky’s notion of the ZPD to analyse the nature of mentor-peer mediation. Witnessing the learners’ use of trial and error strategies during the task-based interview allowed both mentors to support learners through understanding their thinking, prompting them and encouraging them to reflect on their answers and develop more effective strategies. Learners progressed through the ZPD at different paces and in different ways, with ‘aha’ moments happening at different points for individual learners. Their progression in the ZPD seemed to depend on interaction among all participants, which varied according to what was contributed and what requested by each participant. The findings revealed that although there was evidence of learners achieving success at the tasks in task based interviews there were also there were also some learners who experienced difficulties. Additionally, in order to argue that learning was fully realised within the ZPD would have required follow up task based interviews to assess the extent to which learners were able to complete the tasks independently without the scaffolding of mentors. This was not possible within the scope of this research but would be useful in future research.

- Description: The small, medium and micro-enterprises (SMMEs) are essential drivers to the social and economic growth. These enterprises have an essential role in employment creation and eradication of poverty in South Africa. SMMEs in South Africa are comprised of heterogeneous groups of businesses in various sectors including services, manufacturing and agriculture. This study investigated the effect of social capital on the performance of SMMEs. Thus, the primary objective of the study was is to investigate the impact of social capital on the performance of SMMEs in Makana Municipality, and the secondary objectives were to determine the effect of bonding social capital on the performance of SMMEs and determine the effect of bridging social capital on the performance of SMMEs. This study discovered that all three forms of social capital, namely: bonding, bridging and linking social capital have a positive effect on the performance of SMMEs. In order to collect data, the researcher distributed questionnaires to the sampled SMMEs in the towns within the Makana Municipality. All the questionnaires were completed by the respondents. The researcher did not interfere in this process but helped where necessary. Prior to the distribution of questionnaires, validity and reliability were ensured in order to eliminate problems in the questionnaires. A total of 126 questionnaires were distributed. To scale the responses in the questionnaires, Likert scale was used in this study. The sections in questionnaires were measuring the extent to which social capital contributes to the performance of SMMEs. Of the 126 questionnaires that were distributed, only 98 questionnaires were returned and used in this study. Thus, the response rate was 71% which is high. Because social capital affects the performance of SMMEs, this proves further the need for government to support these businesses. This study made a theoretical contribution to the literature on social capital and its important on the performance of SMMEs. The researcher recommends that all SMMEs across the world consider the effect of social capital on their performance. Given the importance of successful SMMEs in the growth of the country’s economy and, also the role they play in addressing the unemployment problem, it is recommended that all SMMEs consider the positive impact of social capital in their growth.

- Description: Management development in educational contexts is a relatively recent development in South Africa. The Task Team Report on Education Management Development of 1996 drew pertinent attention to the need for education management development in South Africa, and set an agenda for such development. Since then many management development programmes have been launched by both National and Provincial government. However, very little research seems to have been conducted on these programmes, especially on how they have been received. This study seeks to address that need. The study is a qualitative phenomenological investigation of how four secondary school principals experienced and perceived the management development programmes they have attended. In line with a phenomenological approach, the study sets aside preconceived ideas and attempts to describe the phenomenon through the eyes of the participants. Findings suggest that management development programmes are perceived as having a big role to play in the development of school managers, but that the programmes on offer suffer from various shortcomings. These include poor planning, lack of organisational and facilitating skills in presenters, lack of commitment, monitoring and support from the bodies offering the courses, and especially the failure of training programmes to bring about increased confidence and self-awareness among participants. Increased selfawareness can help in personal and organisational renewal and growth, and help to minimise the dependency syndrome among principals. Particular needs highlighted by the findings include training in the new curriculum (Outcomes Based Education), holistic development by experts in all facets of school management, training of School Governing Bodies and development of all educators in management as future managers. These findings may prove helpful to education departments and other bodies in the planning and delivery of programmes for new and incumbent school managers.
