- Description: This mini-thesis investigates some of the nineteenth century socio-cultural ideals that have structured a connection between virtuosic aerial skill and bodily aesthetics. It views the emergence of a style of aerial kineticism that is structured from the gender ideologies of the period. It investigates the continual recurrence of this nineteenth century style amongst contemporary aerial dance works and outlines the possible frictions between this Victorian style of kineticism and contemporary aerial explorations. From this observation, a possible catalyst may be observed with which to relocate and inspire a study of aerial kinetics sans the nineteenth century aesthetic component. This kinesiological catalyst may be viewed in conjunction with the theories of ground-based kinetic theorist, Rudolph Laban’s choreutic study of the body in space. Thus, it may be possible to suggest and introduce a possible practical dance scholarship for aerial dance. This mini-thesis includes an introductory choreological investigation that draws on and integrates the disciplines of kinesiology; choreutic theory; existing aerial kinetic technique; musicology; and the physical sciences.

- Description: The aim of the study was to explore and describe causes of re-offending and the management’s perspective of the effectiveness of programmes being implemented at Nerina One Stop Youth Justice Centre in dealing with re-offenders. Youth re-offending involves breaking of the law and crime. Offending if repeated then develops to be re-offending which is the breaking of the law more than once and this is a dilemma in South Africa as the increase of crime is a challenging issue. A qualitative approach was utilized following an exploratory, descriptive research design as the researcher sought to understand the perspective of the managers at Nerina regarding causes of re-offending and the effectiveness of the intervention programmes aimed at addressing this phenomenon. The researcher conducted face to face interviews with the mangers at Nerina One Stop Youth Justice Centre. For the purpose of this study the population was the total complement of the management staff at the One Stop Youth Justice Centre, this included the personnel of the departments of Justice, Social Development, and South African Police Service who are all involved in rendering services at Nerina. The method of data collection was one on one semi structured interviews and data analysis undertaken according to the steps for qualitative data analysis as proposed by Tesch in Creswell (1994). Guba’s model (Krefting, 1991) was employed for assessing the trustworthiness of the qualitative data. Some of the important findings included the causes of re-offending which included loss of parents, alcohol and drug abuse, inadequate parent role, role of peers and inadequate facilities. Further more from the study suggestions for improving programmes at the One Stop Youth Justice Center were discussed and these include involvement of community, involve more role players, training staff and increasing staff.

- Description: Child Sexual Abuse (CSA) is a societal problem whose origins date back to the times of the ancient Greeks and Romans. It is found in all levels of society, from the wealthiest to the poorest; and the short-term and long-term impacts it has on the lives of the victims, can be devastating. There are many reasons for the occurrence of child sexual abuse, but in all cases, the ultimate accountability rests on the shoulders of the sexual offender. The nature of child sexual victimisation varies from verbal suggestions to violent physical force. Irrespective of which type the child is being subjected to, as the weaker partner in the pedagogical relationship with the adult, s/he is never able to defend herself/himself. The global phenomenon, and the increase in CSA, has given rise to the research question, namely: How does child sexual abuse impact on the school life experiences and academic performance of learners at school? The purpose of this research study was to provide insight into the following issues: • The nature and identification of the symptoms of child sexual abuse; • The manner in which sexually abused children manifest their experiences of sexual abuse at school; • How sexually abused children cope with their learning tasks; and • Recommendations for educators. The literature relating to CSA was reviewed, with the aim of establishing a solid theoretical foundation for the study. CSA has been looked at holistically, encompassing the accepted definitions, the related concepts, the nature of sexual abuse, the prevalence and incidence of CSA, the possible causes, the short-term and long-term impacts, and the suggestions by adult survivors for use by educators in their efforts to help abused learners. 11 In an attempt to provide acceptable answers to the research problem, a mixed- method research design was implemented. The research study was conducted in two phases: Stage 1 consisted of an exploration of the research problem by means of the following question put to the participants: In your experience as an adult survivor of child sexual abuse how did the abuse impact on your school life experiences, including your academic performance? A total of nineteen participants from the Eastern Cape Province shared their experiences, by means of writing their life story as a narrative. Purposive and availability sampling of adult survivors was undertaken. In order to ensure the trustworthiness and authenticity of the research methodology, Guba’s model of data verification was used. Accepted ethical measures were taken into consideration and adhered to during the research. The analysed data were taken directly from the narratives that the individual participants saved onto flashdrives. Consensus by the researcher and coder was reached regarding the identification of themes, categories and subcategories. The following four significant themes emerged, based on the results of the data analysis: Theme One: Health, sexuality and the sexual experiences of sexual abused children and adolescents. Theme Two: The social development of sexually abused children and adolescents. Theme Three: School-related experiences and academic performance of sexually abused children and adolescents. Theme Four: Advice and suggestions from adult survivors for young victims of CSA. 12 Stage 2 offered recommendations to the teachers of learners who are, or have been sexually abused, derived from the findings of Phase 1. The conclusion was reached that CSA does have an impact on the academic performance of learners. Therefore, teachers are in need of a greater understanding and awareness of CSA, in order to help these learners.

- Description: Helichrysum longifolium and H. pedunculatum belong to the Astereceae family and are used extensively in folkloric medicine in South Africa to manage stress-related ailments and as dressings for wounds normally encountered in circumcision rites, bruises, cuts and sores. The in vitro antibacterial time-kill studies, the synergistic potentials, the phytochemical screenings and antioxidant potentials as well as the isolation of the bioactive compounds from the extracts of these two plants were carried out in this study. The in vitro antibacterial activities and time kill regimes of crude extracts of H. pedunculatum was assessed. The extracts was active against both Gram positive and Gram negative bacteria tested at a concentration of 10 mg/ml. Minimum Inhibitory Concentration (MIC) values for all the susceptible bacteria ranged between 0.1 – 35 mg/ml. The average log reduction in viable cell count in time kill assay ranged between 0.17 Log10 to 6.37 Log10 cfu/ml after 6 h of interaction, and between 0.14 Log10 and 6.99 Log10 cfu/ml after 12 h interaction in 1 × MIC and 2 × MIC of the extract. The effect of the aqueous extract was only bacteriostatic on both reference and environmental strains and the clinical isolates were outrightly resistant to aqueous extract. This is worrisome and this could be one reason why, there is an incidence of high death rate resulting from circumcision wounds infection even after treating such wounds with H. pedunculatum leaf. In vitro antibacterial time kill studies of extracts of H. longifolium was assessed. All test bacteria were susceptible to the methanol extract, while none was susceptible to the aqueous extract. Two of the test bacteria were susceptible to the ethyl acetate extract, while ten and seven were susceptible to the acetone and chloroform extracts respectively at the test concentration of 5 mg/ml. The minimum inhibitory concentrations (MICs) ranged between 0.1 and 5.0 mg/ml, while minimum bactericidal concentrations (MBCs) ranged between 1.0 and >5 mg/ml for all the extracts. Average log reductions in viable cell counts for all the extracts ranged between 0.1 Log10 and 7.5 Log10 cfu/ml after 12 h interaction at 1 × MIC and 2 × MIC. Most of the extracts were rapidly bactericidal at 2 × MIC achieving a complete elimination of most of the test organisms within 12 h exposure time. The effect of combinations of the crude extracts of H. pedunculatum leaves and eight antibiotics was investigated by means of checkerboard and time-kill methods. In the checkerboard method, synergies of between 45.83-56.81 percent were observed and this is independent of Gram reaction, with combinations in the aqueous extract yielding largely antagonistic interactions (18.75 percent). The time kill assay also detected synergy that is independent of Gram reaction with a ≥ 3Log10 potentiation of the bactericidal activity of the test antibiotics. We conclude that the crude leaf extracts of H. pedunculatum could be potential source of broad spectrum antibiotics resistance modulating compounds. The interactions between crude extracts of H. longifolium in combination with six first-line antibiotics using both the time-kill and the checkerboard methods were carried out. The time-kill method revealed the highest bactericidal activity exemplified by a 6.7 Log10 reduction in cell density against Salmonella sp. when the extract and Penicillin G are combined at ½ × MIC. Synergistic response constituted about 65 percent, while indifference and antagonism constituted about 28.33 percent and 6.67 percent in the time kill assay, respectively. The checkerboard method also revealed that the extracts improved bactericidal effects of the antibiotics. About 61.67 percent of all the interactions were synergistic, while indifference interactions constituted about 26.67 percent and antagonistic interactions was observed in approximately 11.66 percent. The in vitro antioxidant property and phytochemical constituents of the aqueous crude leaf extracts of H. longifolium and H. pedunculatum was investigated. The scavenging activity on superoxide anions, DPPH, H2O2, NO and ABTS; and the reducing power were determined, as well as the flavonoid, proanthocyanidin and phenolic contents of the extracts. The extracts exhibited scavenging activity in all radicals tested due to the presence of relatively high total phenol and flavonoids contents in the extracts. Our findings suggest that H. longifolium and H. pedunculatum are endowed with antioxidant phytochemicals and could serve as a base for future drugs. Bioactivity-guided fractionation of the leaves of H. longifolium and H. pedunculatum yielded two known compounds. From the n-hexane fraction of H. longifolium a compound was isolated (Stigmasterol) and from the ethyl acetate fraction of H. pedunculatum another compound (β-sitosterol) was isolated. The compounds were isolated and identified using various techniques. The antimicrobial, anti-inflammatory, antioxidant, analgesic and anti-pyretic activities of these compounds have been reported in literatures. In general, the experiments and tests conducted in this study appear to have justified the folkloric medicinal uses of H. longifolium and H. pedunculatum for the treatment of stress related ailments and wound infections and make a substantial contribution to the knowledge base of the use of herbal medicine for the treatment of the microbial infections.

- Description: Friction Stir Welding (FSW) is a solid state welding process invented and patented by The Welding Institute (TWI) in 1991, for joining ferrous and non-ferrous materials1. The FSW of Aluminium and its alloys has been commercialised; and recent interest is focused on joining dissimilar materials. However, in order to commercialise the process, research studies are required to characterise and establish process windows. This research work through material characterisation of the welded joints establishes a process window for the Friction Stir welding of 5754 Aluminium Alloy and C11000 Copper. Furthermore, preliminary studies83,85 on the FSW of aluminium and copper have revealed the presence of intermetallic compounds which are detrimental to the weld qualities. This research work is also aimed at establishing process parameters that will result in limited or no intermetallic formation in the weld. The joint integrity of the resulting welds will also be correlated with the input process parameters. Based on the preliminary investigations conducted, a final weld matrix consisting of twenty seven welds was produced by varying the rotational speed between 600 and 1200 rpm, and the feed rate between 50 and 300 mm/min using three different shoulder diameter tools – 15, 18 and 25 mm to compare the heat input into the welds and to achieve the best results. The welds were characterised through microstructural evaluation, tensile testing, microhardness profiling, X-Ray Diffraction analysis, electrical resistivity and statistical analysis – in order to establish the interrelationship between the process parameters and the weld qualities. viii Microstructural evaluation of the weld samples revealed that the interfacial regions are characterised by mixture layers of aluminium and copper; while 33 percent of the tensile samples are within the acceptable range (> 75 percent joint efficiency). High Vickers microhardness values were measured at the joint interfaces, which corresponded with the intermetallic compounds. The Energy Dispersive Spectroscopy analysis revealed the presence of thin layers of intermetallics in nanoscale at the interfacial regions. The diffractograms of the X-Ray Diffraction analysis showed small peaks for intermetallics in some of the welds. Low electrical resistivities were measured at the joint interfaces. The statistical analysis showed that the downward vertical force, (Fz) can significantly influence the resulting weld qualities. An overall summary of the analysis of the weld qualities - with respect to the shoulder diameter tools employed showed that the 18 mm shoulder diameter tool is most appropriate among the three shoulder diameters considered, and a process window of medium spindle speed of 950 rpm and low-to-medium feed rate between 50 and 150 mm/min is established for FSW of Aluminium and Copper. Welds produced at 1200 rpm and 300 mm/min with low heat input did not have intermetallics formed at the joint interface.

- Description: This study investigates the impact of ICTs for agricultural development in the Alice rural community. The rationale for carrying out the study has to do with the limited access to ICTs by farmers residing in this rural community which in turn affects their productivity and increase in the volume of agricultural production. The core argument of the study is that the use of ICTs has positive spinoffs on agricultural development which leads to improvement in the quality and quantity of agricultural production. Conversely lack of access to ICTs can result in inability to enhance agricultural productivity in rural areas such as Alice. Furthermore, it is argued herein that technological information devices such as ICTs are essential communication and information tools; and as such, should be regarded as useful communication media for disseminating relevant agricultural information to farmers residing in rural communities. In conducting this study theoretical frameworks such as Rogers’ diffusion of innovation and development theories encompassing both the participatory approach and development support communication were presented and argued for as approaches suitable for the study. Triangulations of research methods, such as, qualitative and quantitative methods, were utilized for the collection of data for this study. As is common practice, the triangulation method was used in cross checking and supplementing data/information collected through the utilization of each of the methods. Interviews and questionnaires were used as data collection tools for this study owing to their ability to generate clear and precise responses or answers to the questions posed. The key findings of the study show that the limited access to ICTs in the Alice rural community was caused by factors such as low level of literacy, age and language barriers which in turn affected the adoption of ICTs amongst the Alice farmers. Amongst the recommendations emanating from this study is the idea that the adoption of ICTs for agricultural information can be fast-tracked through the implementation of telecentres/kiosk and information centers for easy access to information and communication services in the rural community.

- Description: This thesis critically examines the nature and purpose of a series of four town-hall-like meetings, the Community Dialogues, held in the townships and suburbs of East London, South Africa, in 2009. They were undertaken by a mainstream, commercial newspaper, the Daily Dispatch, under the banner of the worldwide public journalism movement. Following Christians et al (2009), the thesis sets out a normative framework of media performance in a democracy, including a detailed and critical normative theory of the ‘facilitative role’ proposed and developed by Haas (2007), one of the public journalism movement’s key advocate-theorists. It also draws on a variety of theoretical frameworks and perspectives in the fields of Political Studies and Media Studies to provide an analytical overview of the complex matrix of political and media contexts – at the macro (global), meso (national) and micro (local) levels – that have helped give impetus to the Community Dialogues and also shaped their ongoing operation as a public journalism strategy in the South African context. Following a critical realist case study design, the thesis goes on to provide a narrative account of the Dialogues based on in-depth interviews exploring the motivations, self-understandings and perceptions of those journalists who originated, directed and participated in this project, as well as observation of a Community Dialogue, and an examination of some of the journalistic texts related to the Dialogues. This primary data is then critically evaluated against normative theories of press performance, especially Haas’s ‘public philosophy’ of public journalism. The thesis found that apart from their undoubted success in generating a more comprehensive and representative news agenda for the newspaper, the Dialogues often fell short of Habermas’s (1989) proceduralist-discursive notion of the ‘deliberating public’, which sees citizens share a commitment to engage in common deliberation and public problem solving. This can be attributed to a number of problems, including some important theoretical/conceptual weaknesses in the Community Dialogues’ project design, the relative immaturity of the project, the domination of civil society by political society in the South African political context, and a number of organisational constraints at the Daily Dispatch. On the other hand, the newspaper’s editorial leadership has shown clear commitment to the idea of expanding the project in the future, establishing a more a more structured programme of community engagement, and nurturing a more sustainable public sphere, including the building of a more dialectical relationship between the Dialogues and civil society.

- Description: The business environment and the economy of the society today are continuously witnessing the impact of globalisation. Telecommunication advancement and transportation has greatly made the impact of globalisation to be felt. Globalisation though argued to have its merits and its demerits have resulted in fierce competition amongst businesses. The banking industry is not isolated from these competitions. Any business wishing to survive and stay profitable in the recent world must be able to compete in the global economy. Hence, for any bank to sustain itself and remain profitable it must be able to withstand the competition in the environment it operates. To be able to compete in the banking industry means delivering better services to customers than competitors. This study presents how the South African banks can satisfy their customers and remain profitable in the face of competition. The South African banking industry consists of local and foreign banks and these banks compete for customers in the environment in which they are located. Increase in different branches by different banks has made the competition even fierce. In other to suggest recommendations for the South African banks to satisfy their customers and become profitable, the researcher identified some problem areas that need to be improved upon. These include customer loyalty, relationship banking and electronic banking. These variables were researched to understand how they affect the banks and the customers and where tested using both a qualitative and a quantitative analysis to ascertain if the customers were satisfied with the banks‟ approach of managing these variables. The results indicated that the customers were satisfied to a lesser extent. Any bank wishing to satisfy its customers and remain profitable in other to compete in the industry needs to satisfy the customer to a large extent. Therefore, recommendations where suggested based on the empirical results to help improve the banking industry‟s ways of attracting and retaining customers. The former will lead to customer satisfaction which again will lead to increased profitability.

- Description: Against a backdrop of increasing globalisation, deregulation, the rapid pace of technological innovation, a growing knowledge workforce, and shifting social and demographic trends, the primary task of management today is the leadership of organisational change (Graetz, 2000:550). In the words of Lussier and Achua Abstract v (2001:9): “The companies that will survive in the new global competitiveness environment are those that can attract and maintain leaders”. The above emphasises the important role of managers during times when change take place in the organisation. Yet employees are often managed inappropriately in a period of change. There are two reasons for this: (1) managers managing change are under pressure which undermines their own performance, (2) organisations often do not possess managers who are skilful at handling change. It is this second reason that will form the focus of this study. Carnall (1999:105) states that managing change effectively requires an understanding of both what is and seems likely to happen and of how people react to change, and a skilful management performance. Leaders must take on more facilitative roles, as competencies in change management become critical to creating and sustaining effective organisations. The major technological advances of today rely heavily on leaders to facilitate change. Leaders need to encourage people to “collaborate, take risks, take responsibility and be accountable for the change process the organisation must continually undergo to maintain a leadership position in its industry”, according to Moran and Brightman (2000:3). They furthermore argue that “change leaders recognise that they are always trying to balance stability and change. It is a delicate balance to accomplish since employees desire order and stability, while organisations must be ready to adapt to changing conditions quickly”. In this rapidly changing world, organisations must become more flexible, more responsive, and more willing to change and adapt. They must create and assimilate new knowledge at an increasing pace, encourage innovation, and learn to compete in new ways. Dess and Picken (2000:30) argue that the leaders of these organisations must be proactive in facilitating organisational learning and encouraging positive adaptation to external changes. The above shows what an important role leaders/managers have to play in the strategic change process. They need to possess the requisite skills in leadership, problem solving, continuous improvement, team effectiveness, and customer service in order to ensure the long-term growth and stability in the organisation which change can bring about. This research project will identify the various skills needed to successfully manage a change initiative.

- Description: In South Africa, the performing arts have contributed to enhancing national identity and distinctiveness despite coming up against weak legislation, policy and infrastructure to support their growth and proliferation (Fredericks, 2005: 9). Coupled with a decline in both government and consumer support and the contradictory disparity between valuing the arts and the funding of the arts, theatre companies can no longer rely on the comfort of external subsidies and financial support. In order to be economically viable and sustainable to ensure their survival, there is an increasing demand for theatre companies to look to novel ways of increasing audience demand for theatre and improving audience attendance. However, instead of risking artistic integrity and the performance product to satisfy the market, this research suggests that promotion and development of theatre at arts festivals provides a platform to access a wider theatre-going public, which therefore facilitates a change in the market focus toward appreciation of the product (production). It explores leading arguments pertaining to the attendance of arts and cultural events, namely, Peterson and Simkus (1992), later updated by Peterson‟s (2005)„omnivore-univore‟ argument. The argument purports cultural consumption as binary in nature: either significant and diverse or limited, if not absent altogether. Supported by a number of case-studies, including Chan and Goldthorpe (2005) and Montgomery and Robinson (2008) and Snowball et al. (2009), the investigation challenges Bourdieu‟s (1984) theory on cultural distinction as well as the homology and individualisation argument. In determining the factors that influence cultural taste and consumer behaviour, including motivators and inhibitors of attendance and a predominant emphasis on audience risk and information asymmetry, the research was placed in a local context, providing an overview of the socio-economic theatre environment in South Africa. It investigated the nature, structure and impact of local festivals (as events) in changing audience demand and theatre attendance. With specific reference to the South African National Arts Festival (NAF) the research notes the effects of Hauptfleisch‟s „eventification‟ phenomenon on univore attenders and therefore expands the omnivore-univore theory to include a new breed of attender: the “Festivore”. A case study explored the “Festivore” hypothesis through empirical research, surveys and face-to-face qualitative interviews and on-seat questionnaire responses by festival attenders. Personal interviews and communication was also carried out with leading experts in the field. The data was then analysed using SPSS 13 electronic statistical analysis programme to determine the socio-demographics and the factors that affect theatre attendance of existing, as well as potential target, theatre audiences at the National Arts Festival The study concluded that South African theatre attenders are generally omnivorous consumers and that, more importantly, there seems to be a shift towards „festivorous‟ consumption. Furthermore, evidence supports the development and proliferation of festivals as a means not only to support and promote the arts in South Africa but, more importantly, to generate new theatre audiences and entrench theatre attendance into South African culture.

- Description: SMEs fulfil an important role in the long-term growth and development of the economy of the country. The development and growth of construction SMEs are important for all countries, as a strong SME base has the capacity to produce a high-quality infrastructure for the country. Construction SMEs also stimulate economic activity in other sectors of the economy. Research has, however, shown that the failure rate of small businesses within the first five years is high in South Africa. Reseatch has also indicated that the lack of long-term planning and the lack of strategic thinking are major contributing factors to the business failure of SMEs. SMEs operating in the construction industry are faced with the same challenges as their counterparts in other sectors of the economy, but in addition to those difficulties, construction SMEs also have to deal with the unique characteristics of the industry that have adverse implications for them. The construction industry has experienced considerable growth and success, in the past decade, particularly as a result of the government's considerable infrastructural spending, especially in the run-up to the 2010 FIFA World Cup. The growth in the construction industry has, however, not resulted in similar results for Construction SMEs; and research has shown that most of them have not developed into more established entities. In fact, in the Eastern Cape, 91 per cent of all registered contractors fall within the lowest level of the Construction Industry Development Board's classification system. Many construction SMEs perform poorly, but among them there are those that have the potential to grow and develop into larger more established entities. Research has shown that contractor development programmes aimed at assisting the growth and development of construction companies have been successful in increasing participation in the industry, but not in ensuring that small enterprises grow into self-sustainable established enterprises. In contrast, the research has shown that SMEs that practice strategic management perform better, and that there are many advantages for SMEs in applying strategic management principles. This study, therefore, investigates how strategic management can be applied to address the problems faced by construction SMEs, and to exploire techniques and tools of strategic management that can make a significant contribution to their growth and development.

- Description: Hermannia incana Cav. (Sterculiaceae), known as sweet yellow bells, is a medicinal plant used by the people of the Eastern Cape for the treatment of stomach-ache and diarrhoea. It has purgative and diaphoretic effects. It is a prostrate herb with yellow flowers and sparsely hairy and slightly glandular leaves, occurring in grassland and marshes in the Eastern Cape Province of South Africa. Based on the ethnomedical uses of this plant, the research project was designed to evaluate its antidiarrhoeal and toxicological properties. An ethnobotanical study of plants used for the treatment of diarrhoea in the Eastern Cape Province was carried out, using a questionnaire which was administered to herbalists, traditional healers and rural dwellers. This survey indicated a total of 17 plant species from 14 families. Elephantorrhiza elephantine (Burch.) Skeels, Hermannia incana Cav., Pelargonium reniforme Curt., Alepidea amatymbica Eckl. & Zeyh. and Bulbine latifolia (L.f.) Roem. et Schult. were the most frequently mentioned and highly recommended plants for the treatment of diarrhoea by both the traditional healers and rural dwellers. The root, bark and leaves are the common parts of plants used, while decoctions and infusions are the main methods of preparation. The agar dilution method was used to study the antimicrobial activity. The methanol extracts of the plant showed appreciable activity against Gram-positive and Gram-negative bacteria at concentrations ranging from 0.5 to 7.0 mg/ml. The acetone and water extracts of both the leaves and the roots showed moderate activity against Gram positive bacteria and less activity against Gram negative bacteria. All the extracts inhibited the growth of the fungi Aspergillus flavus, Aspergillus niger, and Mucor hiemalis with growth inhibition ranging from 54.31 percent to 96.67 percent at 0.1-10 mg/ml. None of the extracts suppressed the growth of Candida albicans at the maximum concentration (10 mg/ml) tested. iii In the in vivo antidiarrhoeal evaluation using Wistar rats, the aqueous extract at all the doses tested, significantly prolonged the time of induction of diarrhoea and also reduced the frequency of diarrhoeal episodes and fecal parameters (total number, number of wet, fresh and dry weight and water content of the faeces). The percentage inhibition of defecation and intestinal content (enteropooling) were increased in dose dependent manner. The doses also reduced the intestinal transit time of charcoal, masses and volumes of intestinal fluid (gastrointestinal motility). These results are indications of antidiarrhoeal property of H. incana leaf extract with the 600 mg/kg body weight of the extract being the most effective. In the toxicological evaluation using Wistar rats, the oral administration of the extract did not produce any significant effect on the liver and kidney body weight ratios, RBC, HB, PCV, MCV MCH, MCHC, RCDW, WBC, neutrophils, monocytes and basophils cholesterol, triacylglycerol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and atherogenic index. The extract also did not affect the levels of sodium, potassium, chloride, inorganic phosphorus, urea, creatinine, total protein, globulin, albumin, total and conjugated bilirubin. The activities of alkaline phosphatase, gamma glutamyl transferase and alanine aminotransaminase in the serum were increased by the extract whereas aspartate aminotransaminase was decreased. The levels of LUC, platelets, lymphocytes and eosinophils were significantly affected at 600 mg/kg body weight. The available evidence in this study suggests that the extract of H. incana leaf is mild, parameter and dose specific. The structure and distribution of foliar appendages on the leaves of this plant were investigated with the JEOL (JSM-6390LV) scanning electron microscope (SEM). Both glandular and non-glandular trichomes were observed. Long stalked glandular trichomes were present on both the abaxial and adaxial surfaces while short stalked glandular trichomes were present only on the adaxial surface. Glandular trichomes were capitate while nonglandular trichomes were stellate with many arms. Energy dispersive X-ray spectroscopyiv SEM showed that Al, Ca, K, Na, Ti and Si were the major constituents of the crystals analyzed from the leaf surfaces. The phytochemical screening of H. incana revealed the presence of bioactive antidiarrhoeal agents such as alkaloids, tannins, saponins, phenolics, triterpenes, cardiac glycosides, flavonoids, cardenolides and dienolides. Two flavonoids, epicatechin and 3, 5, 7, 2’ tetra-hydroxy flavone-3- O--D-glucopyranoside were isolated from the leaves of the plant through bio-active guided fractionation. Both these compounds were screened against diarrhoea causative organisms (Echerichia coli, Shigella flexneri, Bacillus cereus and Staphylococcus aureus) and exhibiting minimum inhibitory concentrations ranging from 12.5 to 100 μg/ml. The findings from this research have generally justified the traditional use of this plant for the treatment of diarrhoea in this province.

- Description: The objectives of this study were to first identify the decision-making bodies structures in the Buffalo City Municipality. Secondly, to assess compositions, powers and functions of such identified bodies or structures. The field study was limited to the administrative jurisdictions of the Buffalo City Municipality; however, the findings and recommendations were applicable to all municipalities in South Africa with the same or similar decision-making like the Buffalo City Municipality. In order to achieve the research objectives, a review of the relevant literature was done. It began by first looking at the constitutional and other legislative provisions establishing the Municipal government system or concept. The literature review looked at the powers and functions given to municipal governments by such constitutional provisions and how effective are such powers exercised. The literature further highlighted the role of trade unions participation and civil society groups in the smooth and effective administration of the municipality and in making the Integrated Development Planning a successful one. The data collection was done by means of questionnaire, focus group discussions complimented by face-to-face interviews. Forty respondents were sampled from six different trade unions and top municipal management. The data collected were analysed thematically with the use of frequency tables, pie charts and histograms. The findings of the study showed among other things that, the highest decision-making body in the municipality is the municipal council supported by various committees, boards and directorates. All the legislative and executive powers are vested in the municipal council. Again, it became known that, the municipal workers unions participate effectively in labour related issues whereas the non-municipal workers unions participate poorly in all consultative processes. In conclusion, there is the urgent need to bring all stakeholders including trade unions in the municipality during decision-making processes in order promote sustainable development in the municipality.

- Description: This study explores women’s access to land under the customary tenure system. It examines how the changes in land tenure, access and rights to land as a consequence of HIV/AIDS are affecting agricultural productivity, food security and poverty, with a specific focus on women who have lost their husbands to HIV/AIDS in Zvimba. Zvimba is a village community located in Zvimba District in the Mashonaland West Province of Zimbabwe. The study also discusses policy responses designed to cushion the impact of HIV/AIDS on local communities especially women living with HIV/AIDS. The study highlights the vulnerability of widows to land rights violations, mainly inflicted by relatives but sometimes by the wider community. The main form of abuse encountered included the use of abusive language, threats of evictions and at times, beatings. The legal route for seeking redress was rarely used. Fear of witchcraft, low educational levels and fear of causing conflict between children and their paternal relatives also led widows to abandon the fight for their rights. The study further reveals that widows are heavily exposed to dispossession of their land rights. HIV/AIDS has increased the vulnerability of widows and other women to threats and dispossession of their land and other property rights. Dispossession of arable fields was observed in the four wards. The dispossessions and threats to livelihoods were directly related to the HIV positive status of the widows. The findings from this study illustrate the predominant role that male members of the household or family have over land. Thus, culture and traditional practices still affect women in other cases, disadvantaging them in favour of men, as in inheritance of land and property in the household.

- Description: Through an exploration of both sculptural and thought processes undertaken in making my Masters exhibition, ‘Hippocampus’, I unpack some possibilities, instabilities, and limitations inherent in representation and visual perception. This thesis explores the Hippocampus as image (seahorse) and concept (brain-structure involved in cognitive mapping of space). Looking at Gilles Deleuze’s writings on representation, I will expand on the notion of the map as being that which does not define and fix a structure or meaning, but rather is open, extendable and experimental. I explore the becoming, rather than the being, of image and concept. The emphasis here is on process, non-representation, and fluidity of meaning. This is supportive of my personal affirmation of the practice and process of art-making as research. I will refer to the graphic prints of Maurits Cornelis Escher as a means to elucidate a visual contextualization of my practical work, particularly with regard to the play with two- and three-dimensional space perception. Through precisely calculated ‘experiments’ that show up the partiality of our visual perception of space, Escher alludes to things that either cannot actually exist as spatial objects or do exist, but resist representation. Similarly I will explore how my own sculptures, although existing in space resist a fixed representation and suggest ideas of other spaces, non-spaces; an in-between space that does not pin itself down and become fixed to any particular image, idea, objector representation.

- Description: Currently, clinical trials in patients are required by most regulatory authorities for the assessment of bioequivalence of topical products where the drug is not intended for systemic absorption. Hence there is a dire need for suitable methods for the assessment of bioavailability and bioequivalence of such products since clinical safety and efficacy studies are expensive, time-consuming and require very large numbers of patients. Except for topical corticosteroid products where the human skin blanching assay/vasoconstrictor assay has been approved by the US FDA for bioequivalence assessment of those products, no other method has been “officially” approved for use in those investigations. However, a few alternative methods such as tape stripping and microdialysis have been pursued and considered to have the potential for use in ioequivalence/bioavailability studies. The human skin blanching assay was used to assess the bioequivalence of commercially available topical products containing 0.05% clobetasol propionate. Both visual and chromameter data were obtained and a commercially available topical corticosteroid product, Dermovate® cream was used as both the “Test” and the “Reference” product. The results indicated that both visual and chromametric assessments were comparable to each other and that either could be used for the assessment of the bioequivalence of topical products containing clobetasol propionate. The screening procedure was optimized to identify potential “detectors” for inclusion in the bioequivalence studies. This resulted in fewer subjects being required in a bioequivalence pivotal study, still having the necessary power to confirm bioequivalence using the human skin blanching assay. Another objective of this research was to re-visit tape stripping and other possible alternative methods such as dermal microdialysis and to optimize these procedures for bioequivalence assessment of topical formulations where the drug is not intended for systemic absorption. In the past few decades, tape stripping has been used to investigate bioavailability/bioequivalence of various topical formulations. This technique involves the removal of the stratum corneum to assess drug penetration through the skin. A draft FDA guidance for tape stripping was initially published but was subsequently withdrawn due to high variability and poor reproducibility. This research project used an optimized tape stripping procedure to determine bioavailability and establish bioequivalence between three commercially available formulations containing 0.05 % m/m clobetasol propionate. Furthermore, tape stripping was validated by undertaking a study to assess the bioequivalence of a 0.05% topical cream formulation (Dermovate® cream) using the same cream as both the “Test” and “Reference” product, in which bioequivalence was confirmed. The findings highlight the potential of tape stripping as an alternative method for the assessment of bioequivalence of clobetasol propionate formulations and may possibly be extended for use in other topical products. Microdialysis is another useful technique that can assess the penetration of topically applied substances which diffuses through the stratum corneum and into the dermis. Microdialysis has previously been successfully used for in vivo bioavailability and bioequivalence assessments of topical formulations. However, the drugs which were under investigation were all hydrophilic in nature. A major problem with the use of microdialysis for the assessment of lipophilic substances is the binding/adherence of the substance to the membrane and other components of the microdialysis system. As a result, this necessitates the development of a microdialysis system which can be used to assess lipophilic drugs. Intralipid® 20% was investigated and successfully utilized as a perfusate to recover a lipophilic topical corticosteroid, clobetasol propionate, in microdialysis studies. Hence, the bioavailability of clobetasol propionate from an extemporaneous preparation was determined in healthy human volunteers using microdialysis. These findings indicate that in vivo microdialysis can be used to assess lipophilic drug penetration through the skin. A novel approach to investigate drug release from topical formulations containing 0.05% clobetasol propionate using in vitro microdialysis was also undertaken. The in vitro findings were found to be in agreement with the results obtained using tape stripping to assess bioequivalence of the same commercially available products, namely Dermovate® cream, Dovate® Cream and Dermovate® ointment. These results indicate the potential to correlate in vitro with in vivo data for bioequivalence assessment of such topical dosage forms.

The human skin blanching assay was used to assess the bioequivalence of commercially available topical products containing 0.05% clobetasol propionate. Both visual and chromameter data were obtained and a commercially available topical corticosteroid product, Dermovate® cream was used as both the “Test” and the “Reference” product. The results indicated that both visual and chromametric assessments were comparable to each other and that either could be used for the assessment of the bioequivalence of topical products containing clobetasol propionate. The screening procedure was optimized to identify potential “detectors” for inclusion in the bioequivalence studies. This resulted in fewer subjects being required in a bioequivalence pivotal study, still having the necessary power to confirm bioequivalence using the human skin blanching assay. Another objective of this research was to re-visit tape stripping and other possible alternative methods such as dermal microdialysis and to optimize these procedures for bioequivalence assessment of topical formulations where the drug is not intended for systemic absorption. In the past few decades, tape stripping has been used to investigate bioavailability/bioequivalence of various topical formulations. This technique involves the removal of the stratum corneum to assess drug penetration through the skin. A draft FDA guidance for tape stripping was initially published but was subsequently withdrawn due to high variability and poor reproducibility. This research project used an optimized tape stripping procedure to determine bioavailability and establish bioequivalence between three commercially available formulations containing 0.05 % m/m clobetasol propionate. Furthermore, tape stripping was validated by undertaking a study to assess the bioequivalence of a 0.05% topical cream formulation (Dermovate® cream) using the same cream as both the “Test” and “Reference” product, in which bioequivalence was confirmed. The findings highlight the potential of tape stripping as an alternative method for the assessment of bioequivalence of clobetasol propionate formulations and may possibly be extended for use in other topical products. Microdialysis is another useful technique that can assess the penetration of topically applied substances which diffuses through the stratum corneum and into the dermis. Microdialysis has previously been successfully used for in vivo bioavailability and bioequivalence assessments of topical formulations. However, the drugs which were under investigation were all hydrophilic in nature. A major problem with the use of microdialysis for the assessment of lipophilic substances is the binding/adherence of the substance to the membrane and other components of the microdialysis system. As a result, this necessitates the development of a microdialysis system which can be used to assess lipophilic drugs. Intralipid® 20% was investigated and successfully utilized as a perfusate to recover a lipophilic topical corticosteroid, clobetasol propionate, in microdialysis studies. Hence, the bioavailability of clobetasol propionate from an extemporaneous preparation was determined in healthy human volunteers using microdialysis. These findings indicate that in vivo microdialysis can be used to assess lipophilic drug penetration through the skin. A novel approach to investigate drug release from topical formulations containing 0.05% clobetasol propionate using in vitro microdialysis was also undertaken. The in vitro findings were found to be in agreement with the results obtained using tape stripping to assess bioequivalence of the same commercially available products, namely Dermovate® cream, Dovate® Cream and Dermovate® ointment. These results indicate the potential to correlate in vitro with in vivo data for bioequivalence assessment of such topical dosage forms.

- Description: This research study has emerged as a result of my concern regarding the apparent low self-efficacy amongst initial teacher education students in my mathematics education classes. It also reflects a reported renewed interest in values, and the promotion of excellence in education. The effects of a values-based approach to mathematics education towards improving students’ self-efficacy and promoting excellence have been investigated, grounded within my ontology of excellence in mathematics education, which incorporates the values of respect, fairness, accountability, honesty and compassion. An inquiry-based teaching and learning approach formed the framework within which the study took place. Notions of ‘new scholarship’, premised on the view that teaching is about engagement in participatory learning, and the development of communities of creative students, provided the theoretical framework. Both quantitative and qualitative data gathering methods were used. Data-collection tools included affective-disposition statements, interviews, journal entries, as well as a video recording of a mathematics education lesson. The quantitative and qualitative data generated suggest improved levels of self-efficacy amongst the students who participated in the study. The data also suggest that a valuesbased approach to teaching can be used as an effective approach by mathematics teachers – and mathematics teacher educators – for the purpose of promoting the pursuit of excellence. As teacher education worldwide is currently characterised by a lack of vitality in teacher preparation (Grossman, 2008), the findings of this study should provide insights for teacher educators, teachers and policy makers who wish to promote mathematics self-efficacy, excellence and facilitate enhanced vitality within the teaching profession.

- Description: The appreciation by leadership of the culture of an organisation plays an important role in the success of that organisation. Leadership and organisation culture are an inextricable part of the life of an organisation. The shared assumptions and beliefs of the individual within an organisation shape its culture. My study investigates the aspects of school culture and, further, looks at its link to the success of an organisation, and at the leadership style that influences such an organisation. My research, conducted in the interpretive paradigm, is a case study which was carried out at a public secondary school in the capital city of Windhoek, in Namibia. Since the school was built during South African rule, it was intended mainly for white children. Since independence, it has undergone transformation and is currently integrated, accommodating learners from different cultural backgrounds. It is a successful school, with a good reputation for its discipline and academic excellence. I chose this school deliberately, for those reasons. My findings are that there are aspects of culture which maintain its creation and perpetuate the existence of a particular culture at the school. This school’s culture is embedded within the Christian faith, and there are deliberate rituals and ceremonies put in place to enhance the creation and maintenance of the values that inform its culture, and the school leadership, management, teachers and student council members have a central role in this regard. My study shows that the creation, understanding and appreciation of beliefs and values of the individual within the organisation enable the consequent creation of the shared vision and values that ultimately lead to the foundation and maintenance of a strong culture.

- Description: Although the occurrence of wars between states has been in decline, the same cannot be said of conflict within states – especially when considering the innumerable ‘Civil Wars’ said to have occurred since the end of the Cold War. In this context the use of the word ‘innumerable’ is qualified more by the variance in how ‘Civil War’ is understood as a concept (leading to different claims as to how many conflicts of this kind may have occurred over a period of time) and less by their large number. Claims regarding the occurrence of ‘Civil War’ suggest this type of conflict to be the dominant form at least since the end of World War Two. This prevalence in the face of a decline in inter-state warfare has afforded greater interest to ‘Civil War’ as a topic of inquiry. The understanding that ‘Civil Wars’ have with time increased in their occurrence and changed in their nature comes under investigation in this thesis and is seen as problematic in that the means by which a phenomenon is measured (i.e. through its nature) must be fixed so as to measure the frequency of that phenomenon. Using Social Constructivism as a theoretical lens of inquiry, sense is made of this understanding and, furthermore, the true meaning behind the claim that ‘Civil War’ has changed is revealed. The empirical evidence that accompanies this theoretical work exists in the American Civil War of 1861–1865 and the debate over the conflict in Iraq following the U.S. invasion in 2003. This debate is used as a means by which to bring the contestation over the notion of ‘Civil War’ to the fore, while a comparison of this conflict with the quintessential American Civil War reveals the migration of the term.
