- Description: The therapeutic potential of stem cells is already being harnessed in clinical trails. Of even greater therapeutic potential has been the discovery of mechanisms to reprogram differentiated cells into a pluripotent stem cell-like state known as induced pluripotent stem cells (iPSCs). Stem cell nature is governed and maintained by a hierarchy of transcription factors, the apex of which is OCT4. Although much research has elucidated the transcriptional regulation of OCT4, OCT4 regulated gene expression profiles and OCT4 transcriptional activation mechanisms in both stem cell biology and cellular reprogramming to iPSCs, the fundamental biochemistry surrounding the OCT4 transcription factor remains largely unknown. In order to analyze the biochemical relationship between HSP90 and human OCT4 we developed an exogenous active human OCT4 expression model with human OCT4 under transcriptional control of a constitutive promoter. We identified the direct interaction between HSP90 and human OCT4 despite the fact that the proteins predominantly display differential subcellular localizations. We show that HSP90 inhibition resulted in degradation of human OCT4 via the ubiquitin proteasome degradation pathway. As human OCT4 and HSP90 did not interact in the nucleus, we suggest that HSP90 functions in the cytoplasmic stabilization of human OCT4. Our analysis suggests HSP90 inhibition inhibits the transcriptional activity of human OCT4 dimers without affecting monomeric OCT4 activity. Additionally our data suggests that the HSP90 and human OCT4 complex is modulated by phosphorylation events either promoting or abrogating the interaction between HSP90 and human OCT4. Our data suggest that human OCT4 displays the characteristics describing HSP90 client proteins, therefore we identify human OCT4 as a putative HSP90 client protein. The regulation of the transcription factor OCT4 by HSP90 provides fundamental insights into the complex biochemistry of stem cell biology. This may also be suggestive that HSP90 not only regulates stem cell biology by maintaining routine cellular homeostasis but additionally through the direct regulation of pluripotency factors. , Thesis (PhD) -- Faculty of Science, Biochemistry and Microbiology, 2015

- Description: The objective of the study was to determine glycolytic potential and meat quality from Dorper and Merino sheep of both sexes slaughtered at a commercial abattoir. Dorper (n=52) and Merino (n= 48) breeds aged eight years, consisting of 50 intact rams and 50 non-pregnant ewes were used in the study. The sheep used in the study were reared, transported and lairised under identical conditions. Blood samples were collected at exsanguination for the measurement of glucose, lactate and cortisol levels. Samples were also collected from the Muscularis longmissius thoracis et lumborum (LTL) for the measurement glycogen, lactate levels, pH decline and colour. Correlations amongst blood stress indicators, muscle metabolites and meat quality attributes were also determined. Sex and breed had no effect on muscle glycolytic potential, glycogen and lactate levels from Dorper and Merino sheep of both sexes at the abattoir. Although sex and breed had an effect on pre-slaughter stress indicators (lactate and cortisol) collected at exsanguination. Ewes had higher levels of blood lactate (7.4 3 ± 0.49 mmol/L) and cortisol (293.92 ± 14.32 nmol/L) than the rams which had (5.19 ± 0.49 mmol/L) and (179.50 ± 14.32 nmol/L) lactate and cortisol levels, respectively. Furthermore, higher levels of lactate were observed in Dorper (7.54 ± 0.42 mmol/L) compared to the Merino sheep (4.97 ± 0.49 mmol/L). Meat pH decline and colour were also significantly affected by sex and breed. Ewes had higher levels of at pH45 minutes post slaughter (7.05 ± 0.04), pH3 hours (6.45 ± 0.04) , pH24 hours (6.00 ± 0.03), a* (14.31 ± 0.33) , b* (8.84 ± 0.29), H* (31.47 ± 0.73) and C* (16.75 ± 0.24) compared to the rams which had pH45 minutes (6.44 ± 0.04), pH3 hours (6.12 ± 0.04), pH24 hours (5.88 ± 0.03), a* (12.25 ± 0.33), b* (7.00 ± 0.29), H* (29.36 ± 0.73) and C* (14.15 ± 0.42) values. Moreover, Merino sheep had higher levels of L* (38.17 ± 0.48) and H* (31.59 ± 0.74) compared to the Dorper which had (36.39 ± 0.46) and (29.33 ± 0.71) L* and H* values, respectively. Blood cortisol was also positively correlated (P < 0.05) to glucose (r = 0.27), lactate (r = 0.37) but was negatively correlated (P < 0.001) to meat lightness (r = -0.44). Furthermore, blood cortisol was positively correlated (P < 0.001) to pH45 (r = 0.34), pH24 (r =0.22), meat yellowness (r = 0.24) and chroma (r = 0.37), but was negatively correlated to meat lightness (r = -0.47). Glycolytic potential was positively correlated (P < 0.001) to muscle glycogen levels (r = 0.66) and muscle lactate (r = 0.71).

- Description: It is well established that non-timber forest products make significant contributions to rural incomes throughout most of the developing world. NTFP use frequently raises concerns about the sustainability of, or ecological impacts associated with, NTFP harvesting, as well as local contextual factors which may limit or reduce the impacts. Here we test the conceptual model first advanced by Uma Shaanker et al. (2004) relating to the factors that may limit or exacerbate the ecological impacts associated with NTFP harvesting. These were the extent of local dependence on NTFPs, the degree of marketing and the level of local ecological knowledge. Data were collected via household questionnaires and ecological surveys of woody plants from eight villages throughout South Africa. We found no significant relationships between measures of ecological impact with local ecological knowledge or market proximity and engagement. There was a strong positive relationship between ecological impacts and NTFP dependency as indexed through mean annual direct-use value for NTFPs. This indicates that the higher the dependency and demand for NTFPs, the greater is the possibility of high impacts to the local environment. However, other contextual drivers not included in the original Uma Shaanker et al. (2004) model may also play a role, particularly the strength of local resource governance institutions.

- Description: Land art, and some installation art, is usually aimed at relatively temporarily manipulating the surface of the earth. AfrikaBurn takes place annually in the near-desert of the Tankwa Karoo, South Africa. It is a communal event unique to Africa, and manifests as a fleeting week-long series of interventions in the natural environment, partially aimed at creating and then actively destroying free-standing public sculptures, some of which are huge and intricate. AfrikaBurn gives any one of the thousands of participants an opportunity to be inspired on any scale to generate artworks that take into account a principle that no debris whatsoever is left behind on the surface of the earth after a week-long celebration of creative energies. Unlike, for instance, an artwork built on the edge of the Indian Ocean in the Eastern Cape, where rough tidal seas would ensure gradual destruction, at AfrikaBurn, the sacrificial method of choice is controlled rapid burning, under the direction of a specified firemaster. This paper seeks to unbundle some aspects of land and installation art in Southern Africa with specific reference to AfrikaBurn 2015 events and anti-fracking initiatives. This is within a context that takes into account recognition that even seemingly durable public sculptures are subject to change and may even physically disappear with the passing of time.

- Description: Vale van der Merwe has been working as a ceramic artist for the past five years, and in that time has developed a remarkably diverse repertoire of both thrown and handbuilt works. These include rapidly thrown utilityware as well as carefully conceived sculptural works that engage with ideas rather than primarily with function. She also makes full use of opportunities offered by high-temperature woodburn firings, and despite works collapsing while being made, breaking while being carried to the kiln and slumping during firing, she has used such occasions as opportunities for learning rather than despondency. Van der Merwe is also an actively hands-on ceramic artist who engages with all levels of tasks associated with studio ceramics in a village setting, so has found herself, for example, both creating a new chimney for the kiln, and simultaneously leading discussion around concepts for new collaborative exhibitions. There is a seriousness of intent combined with infectious confidence evident in both her daily presence and ceramics, and it is hoped that she will develop her repertoire and thinkings even further in forthcoming years.

It spread a consciousness idealizing self-sufficient pottery studios where potters were in touch with all aspects of creating utilityware, largely from local materials for local use. Out of this emerged an Anglo-Oriental studio ceramic philosophy of form and practice, associated mainly with hand-made high temperature reduction fired ceramics. These ideas spread to South Africa in the late 1950s, and by the early 1960s local studios were being established along these lines. This studio ceramics movement grew exponentially in South Africa, initiating a phase of Afro-Oriental ceramics that remains a powerful way of life and visual arts influence. This paper seeks to explore aspects of Afro- Oriental studio ceramics in South Africa, with particular reference to the Leach/Hamada/Cardew to Rabinowitz, and Van der Merwe lineage.

- Description: The sale of an entity as a going concern has a number of tax consequences for both the purchaser and the seller. The tax deductibility of a contingent liability upon its transfer from the seller to the purchaser, where the selling price has been reduced by the value of the contingent liabilities transferred, remains uncertain following the decision in Ackermans Ltd v Commissioner for the South African Revenue Service. An expense is either deductible under a specific section of the Income Tax Act, 58 of 1962, or under the general expense provisions in terms of sections 11(a) and 23(g). The Act does not contain a specific section relating to contingent liabilities and therefore a contingent liability will need to be considered for deduction under these sections. The Act further disallows an expense as a deduction under section 23(e), where a reserve is created (for example a leave pay provision). This study analyses the tax deductibility of a contingent liability, where the contingent liability has been transferred from the seller to the purchaser in a sale of an entity as a going concern and the purchase price has been reduced to compensate for the transfer of the contingent liability. The deductibility of the contingent liability was first assessed in terms of the provisions of the Act (sections 11(a), 23(g) and 23(e)) and associated case law. The decision in the Ackermans case and its preceding Income Tax Case 1839 was then analysed in order to establish the principles arising from the decisions. Finally the proposals in the Draft Taxation Laws Amendment Bill, 2011, and the subsequent Discussion Document issued by the South African Revenue Service were discussed. The analysis revealed the continuing confusion surrounding the status quo, thus demonstrating the importance of legislative intervention to provide guidelines for taxpayers.

- Description: Goatfishes inhabit inshore reefs and corals and are commercially important across their distribution in the Western Indian Ocean (WIO). The biogeography of these species in the WIO has not been explored with regards to their levels of diversity and relationships among regions. The genetic connectivity and differentiation of three goatfishes of the genus Parupeneus (P. barberinus, P. macronemus and P. rubescens) was studied using two mitochondrial genes (ND2 and 16S rRNA) and one nuclear gene (RAG1) using specimens from East and southern Africa, islands around the Mascarene plateau, Oman, Maldives and the Red Sea. Haplotype diversities, networks and AMOVA were used to measure genetic variance among localities and defined regional groups. There were high haplotype (HD > 0.9) and low nucleotide diversities (< 0.006) among all species for all gene regions, suggesting high levels of genetic differentiation among different areas, except for the mtDNA 16S data for P. macronemus and P. rubescens. For all three species, the FST population pairwise values revealed significant differentiation in all datasets for most population pairwise comparisons with the Maldives and genetic connectivity with haplotypes being shared among other localities. The 16S and RAG1, AMOVA for P. barberinus revealed a significant (P < 0.05) strong genetic structure among groups, for example P = 0.00 was estimated in the 16S data for four groups (the Maldives, WIO islands, Kenya and eastern mainland). This study found evidence for regional differentiation within the WIO for these three species supporting the presence of genetic breaks among areas. This differentiation could be either due to the historical isolation among areas or due to geographic and oceanic barriers such as the Mascarene Plateau and the Agulhas Current eddies in the Mozambique Channel. The effects of oceanographic features and physical barriers in the species distribution range and the dispersal potential based on the life history features of the species can have an influence on the genetic structuring of a population. It is also important to note that the length of the pelagic larval phase is just one factor affecting dispersal in marine organisms that can also explain the difference in genetic population structure. Unfortunately there is no specific information on the larval dispersal of these three goatfish. Therefore, studies are needed to be conducted on the specific biology and life history strategies of each Parupeneus species. These results suggest the importance of other factors, such as currents, and larval retention that may cause strong differentiation. These factors should also be considered when observing larval dispersal and its effect on population genetic structure. This study support the hypotheses that physical factors, processes (geographic barriers and oceanographic characteristics) and life history parameters need to be studied to understand the genetic differentiation of these Parupeneus reef fishes.

- Description: Goatfishes inhabit inshore reefs and corals and are commercially important across their distribution in the Western Indian Ocean (WIO). The biogeography of these species in the WIO has not been explored with regards to their levels of diversity and relationships among regions. The genetic connectivity and differentiation of three goatfishes of the genus Parupeneus (P. barberinus, P. macronemus and P. rubescens) was studied using two mitochondrial genes (ND2 and 16S rRNA) and one nuclear gene (RAG1) using specimens from East and southern Africa, islands around the Mascarene plateau, Oman, Maldives and the Red Sea. Haplotype diversities, networks and AMOVA were used to measure genetic variance among localities and defined regional groups. There were high haplotype (HD > 0.9) and low nucleotide diversities (< 0.006) among all species for all gene regions, suggesting high levels of genetic differentiation among different areas, except for the mtDNA 16S data for P. macronemus and P. rubescens.

- Description: The focus of this study is on understanding the multiple and interacting factors that hinder or enable municipal planned climate change adaptation, here called barriers and enablers respectively, and their implications for community based adaptation. To do this I developed a conceptual framework of barriers to and enablers of planned climate change adaptation, which informed a systematic literature review of barriers to planned community based adaptation in developing countries. In this framework barriers were grouped into resource, social and physical barriers. I then conducted empirical case study analysis using qualitative research methods in four South African municipalities to understand what barriers and enablers manifested in these contexts. In light of the reflexive nature of my methodology, my framework was adjusted based on my empirical findings, where contextual barriers were found to better represent the empirical results and subsumed physical barriers. I found my framework useful for analysis, but in the empirical cases, barriers and enablers overlaid and interacted so significantly that in reality it was often difficult to separate them. A key finding was that enablers tended to be more about the way things are done, as opposed to direct opposites of barriers. Comparison of barriers and enablers across the case studies revealed a number of key themes. Municipalities struggle to implement climate change adaptation and community based adaptation within contexts of significant social, economic and ecological challenges. These contextual barriers, when combined with certain cognitive barriers, lead to reactive responses. Existing municipal systems and structures make it difficult to enable climate change adaptation, which is inherently cross‐sectoral and messy, and especially community based adaptation that is bottom‐up and participatory. Lack of locally applicable knowledge, funding and human resources were found to be significant resource barriers, and were often underlain by social barriers relating to perceptions, norms, discourses and governance challenges. Enablers of engaged officials, operating within enabling organisational environments and drawing on partnerships and networks, were able to overcome or circumvent these barriers. When these enablers coincided with windows of opportunity that increased the prioritisation of climate change within the municipality, projects with ancillary benefits were often implemented. Analysis of the barriers and enablers identified in the literature and case studies, informed discussion on whether municipalities are able to implement community based adaptation as defined in the literature, as well as the development of recommendations for how municipal planned climate change adaptation and community based adaptation can be further understood and enabled in the future. These recommendations for practice and research include: (a) To acknowledge and understand the conceptual framings of municipal climate change work, as these framings inform the climate change agenda that is pursued, and hence what municipal climate change adaptation work is done and how it was done. (b) The need for further research into the social barriers that influence the vital enablers of engaged officials, enabling organisational environments, and partnerships and networks. (c) To learn from pilot community‐level interventions that have been implemented by municipalities, as well as from other disciplines and municipalities. (d) To develop top‐down/bottom‐up approaches to enable municipal planned climate change adaptation and community based adaptation, that benefits from high level support and guidance, as well as local level flexibility and learning‐by‐doing. (e) To develop viable mechanisms for municipalities to better engage with the communities they serve.

- Description: Goretti Kyomuhendo's Waiting: A Novel of Uganda at War explores the atrocities that ordinary people experience during wartime by placing emphasis on the private suffering and humiliation inflicted on women in the domestic space of the home. This article argues that even if women do not actively feature on the battleground, they are still inadvertently drawn into the war, which has an adverse impact on their lives. Kyomuhendo draws on the experiences of different female characters to problematize the inherently ambiguous symbolic image of the mother, and shows that the violence performed on women's bodies is a result of the interplay between two hegemonic forces, patriarchal authority and state power.

- Description: South Africa has wide ranges of plants among which are leafy vegetables growing in the wild. These wild vegetables have been reported to have high nutritive and medicinal potentials. Yet, there is still high prevalence of malnutrition and micronutrients deficiencies among the low income bracket of the population. Effective utilization of wild vegetables has been proposed as part of the solutions to address the problem of dietary deficiencies among the populace. Their importance is mainly as relish to accompany and complement starch based diets. They are also known to serve as supplements for food which have the potential to improve the health status of its consumers in many rural communities. Cleome gynandra L. (Capparaceae) is one of the underutilized species mentioned during asurvey conducted in Nkonkobe municipality of the Eastern Cape Province, South Africa. The plant is an erect annual herb with alternate, palmately compound leaves and its petals are white, pink or lilac. It grows as a weed in this part of the Province and is usually gathered from the wild for food and medicine. It is commonly found on wastes land, road sides and on grass lands. Therefore, this research work was designed to contribute to the possible domestication of this wild vegetable in order to explore the nutritive and therapeutic potentials which would broaden the food base in the Eastern Cape Province. The ultra-micromorphological features of plants have become an essential tool in proper identification and authentication of several plant species. In the light of this, the micromorphology of Cleome gynandra was examined to reveal the micro-morphological characters of the plantand to determine if micro and macro mineral elements are present using energy dispersive x-rays. The present study revealed the epidermal cells of the leaves to be asymmetric in shape with undulating cell walls having four subsidiary cells around the stomata. The leaves have anomocyctic stomata which are more distributed in the abaxial surface than the adaxial surface. The mean length and width of the guard cells in the abaxial surface are 0.09 ± 0.01 mm and 0.08 ± 0.01 mm respectively while that of adaxial surface are 0.1± 0.01 mm and 0.07 ± 0.01 mm respectively. The energy dispersive x-rays (EDXS) micro-analysis of the leaf revealed the presence of phosphorus, manganese, iron, calcium, sodium, magnesium, potassium and zinc as the major constituents of the crystal deposits present in the stomata pores and the mesophyll. C. gynandra was collected from the wild and analysed for its mineral and proximatecomposition using standard analytical methods. The plant showed high levels of sodium, iron, zinc, calcium and potassium while many other macro and micro minerals were moderately present. Amongst the proximate factors investigated, moisture content was found to be 82.1% while crude fibre and protein contents were 39.9 percent and 31.03 percent respectively. Vitamin C was also high (345.3 mg/100g). The anti-nutrients compositions revealed low concentrations of oxalate (7.4 ± 0.4) and phytate (0.6 ± 0.0) mg/100g. The study revealed high nutritive value of the species growing naturally from the wild. Interest in the phenolic compounds has greatly increased recently because these compounds have been implicated in suppressing the risk of degenerative diseases in humans. The pharmacological properties of plants may be related to their antioxidant capacities and hence there was need to investigate the antioxidant potential using aqueous, ethanolic and acetone extracts of different parts of C. gynandra. The quantities of phenols, flavonoids and flavonols were significantly higher (p < 0.05) in both aqueous and ethanol extracts of the leaf while the concentration of proanthocyanidins was higher in the aqueous stem extract compared to other plant parts. The aqueous extract of the different parts exhibited better ABTS, reducing power and NO radical scavenging abilities than ethanol extract.

- Description: Historical ad hoc allocations of land for biodiversity conservation have led to a biased representation of habitat within the Cape Floristic Region, with Protected Areas concentrated in upland areas at high altitudes and on steep slopes. The field of Conservation Planning developed to ensure that allocations of areas to Protected status no longer result in such bias and rather promotes the persistence of biodiversity. This study reviewed a recent allocation of land to biodiversity conservation within Western Cape of South Africa, using both a quantitative and qualitative approach, to determine their value to biodiversity conservation. The area was previously used for commercial forestry but now has been allocated to conservation land-uses. The allocation was based on the area’s value to the forestry industry. The qualitative approach in this study engaged with relevant stakeholder groups to map priority areas, while the quantitative approach used available data on biodiversity features to map priority areas. Neither approach determined that the area allocated is in its full extent a priority for biodiversity conservation. This indicated that in the current era of Conservation Planning, Protected Areas are still being allocated in an ad hoc manner, as a result of their limited perceived benefit to anthropocentric needs. The future allocation of land to biodiversity conservation should rather integrate expert knowledge and available quantifiable data to ensure that priority areas for biodiversity conservation are being protected.

- Description: This study was originally undertaken to change and improve the way I do my practice at Walter Sisulu University as a Research Associate whose responsibility is to facilitate research capacity development and research excellence within the University, amongst academics and postgraduate students. The success of the Research Resource Centre that I manage depends on the way I promote research culture and research productivity amongst academics and postgraduate students. According to Leedy and Ormrod (2013, p. 2), research is a systematic process that is used to collect, analyse, and interpret data in order to increase my understanding of the phenomenon about interest and concern about a given/identified phenomenon. In this case my own practice changed and improved for the better. The main objective of this study, therefore, was to examine the reasons behind the decline in research productivity in terms of research output and how this could be reversed through action research study intervention in order to enhance research productivity at Walter Sisulu University (WSU). The Department of Higher Education and Training’s (DHET) allocation of research output units for WSU indicated that there was a decline in research output from 2005 to 2010. The extent to which my practice improvement could contribute towards changing or improving research productivity was a question which this study addressed through a quantitative, qualitative and self-reflective action research cyclic inquiry. I organized sample strategies of this study as follows: For quantitative data, I used 120 lecturers as my respondents through questionnaires (females = 47 and males = 73) who were randomly selected; For qualitative data, I used 24 lecturers as respondents who were randomly selected with whom I conducted interviews; and For self-reflective action research cyclic inquiry I used 7 Transformative Education/al Studies (TES) project group members as my focus group. My research findings concluded that the heavy teaching workload at WSU was problematic and lecturers/academics could not devote time to do research. My recommendation is that research should be made compulsory so that academics become aware that at least one or two published articles are required from them, for the benefit of annual university research productivity. Some research participants also recommended that the Research Resource Centre must include programs that focus directly on active participation in research in order to increase the capacity of individual researchers so as to build a critical mass of competent researchers, perhaps by even including incentives as a reward for doing research. According to Koshy (2010), action research is a specific method of conducting research by professionals and practitioners with the ultimate aim of improving practice. My new knowledge, therefore, in respect of how a concerned Research Associate, from a Historically Disadvantaged Institution (HDI), provided the impetus to create a collaborative practice in a higher education institution which was forced to merge with two former technikons (which lacked understanding of what a university means by research productivity and research output). I consequently developed the Nkosinathi Sotshangane’s cyclic practice improvement model through self-reflective action research, from which I believed other research practitioners could learn by doing something similar in their own context.

- Description: The performance management system has become a vital process of retaining skilled employees, helping to improve communication between the employees and management, providing feedback to employees and clear understanding of job expectation. A performance management system assists the firm to identify the ways to improve individual and firm performance and provides the opportunity for discussion about individual career direction and growth within the firm. It provides the opportunity to set employee targets linked to the departmental targets. The performance management system is the catalyst for firms to become globally competitive and be able to meet targets. Over the years the firm has introduced a performance management system to help employees to achieve their targets, which will result in the company meeting its own objectives. The study focused on the factors that affect the performance management system. The objective of the research was to improve the performance management system of the firm. The study was conducted to assess the effect of the following independent variables on the improvement of the performance management system: leadership style, training, organisational culture, reward system and organisational communication. The sample consisted of only the employees of the firm selected for the study. One hundred and fifty (150) questionnaires were distributed, but only seventy-six (76) respondents (response rate = 50.7 percent) participated in the final study. The empirical results revealed that the three independent variables play a very important role in improving a performance management system. These three variables are organisational culture, training, and reward system. Implementing the recommendations that came from these results will go a long way to making sure that the firm will improve its performance management system.

- Description: The performance management system has become a vital process of retaining skilled employees, helping to improve communication between the employees and management, providing feedback to employees and clear understanding of job expectation. A performance management system assists the firm to identify the ways to improve individual and firm performance and provides the opportunity for discussion about individual career direction and growth within the firm. It provides the opportunity to set employee targets linked to the departmental targets. The performance management system is the catalyst for firms to become globally competitive and be able to meet targets. Over the years the firm has introduced a performance management system to help employees to achieve their targets, which will result in the company meeting its own objectives. The study focused on the factors that affect the performance management system. The objective of the research was to improve the performance management system of the firm. The study was conducted to assess the effect of the following independent variables on the improvement of the performance management system: leadership style, training, organisational culture, reward system and organisational communication.

- Description: The perceptions of Nelson Mandela Metropolitan Municipality obstetric unit midwives regarding consulting advanced midwives were researched. Currently South Africa is burdened with an increasing maternal mortality rate despite the control measures that have been put in place. One of those control measures is the skilling of midwives and ensuring that skilled birth attendants assist every woman in confinement. A concern, though, was observed by the researcher that an increasing number of midwives in the country now have an additional qualification in advanced midwifery and yet the maternal and neonatal mortality rates are gradually increasing. The researcher, as a midwife and a midwifery lecturer in that capacity, observed that in the clinical areas midwives prefer to consult with the doctor rather than the advanced midwife. In most cases looking and waiting for the doctor delays the management of the labouring woman as the doctor may not be immediately available. The advanced midwives are supposed to have advanced skills which should be used to assist in the absence of the doctor, particularly in the midwife obstetrics units. The study objectives were firstly, to describe and explore the perceptions of NMM obstetric unit midwives regarding consulting with advanced midwives. Secondly, based on the results of the study, to make recommendations to the managers of the obstetric units within the NMM that will enhance consulting between advanced midwives and midwives in obstetric units. The study was quantitative in nature and utilised an explorative, descriptive and contextual design. Sampling was made possible through simple random probability sampling using the non-replacement approach. The method of data collection was by self-administered questionnaires that were developed by the researcher under the guidance of a qualified and experienced statistician and researcher and the supervision of the research supervisor. Data was collected during July and September of 2014. One hundred and thirty questionnaires were distributed and ninety four were returned. Responses were captured on a spread sheet for easy and accurate calculation and the numerical data was categorized, ordered and manipulated with the help of a statistician using the software package Statistica Version 21 to ensure efficacy of the results The findings were presented by describing the biographic profile of participants, their competence in the identification and management of high risk situations, their consultation with advanced midwives in high risk situations, their reasons for not consulting advanced midwives and a description of factors that might encourage midwives to consult the advanced midwives. Literature controls were utilized to compare findings with current views of other researchers. Trustworthiness was maintained by observing the principles of reliability and validity. The ethical considerations of confidentiality, anonymity and protection of the participants from harm were maintained by the researcher. The findings revealed that there were significant numbers of midwives with many years of clinical experience and years in the units. The age difference of the midwives in the obstetrics units was seen to be an added advantage to the care of women as the young and old could complement each other with the latest information and experience in dealing with midwifery related emergencies respectively. The difference in gender was as expected but did not have an influence on the non-consulting with advanced midwives by the midwives who are working in the obstetrics units. Also, the limited confidence of midwives regarding their performance of certain low risk skills and their confidence in the performance of the advanced midwives was a reason to consult with the advanced midwives in their areas of speciality. Based on these findings, the researcher attended to the second objective and made the necessary recommendations to the managers of the obstetric units within the NMM to enhance consulting with advanced midwives by midwives in obstetric units. Midwives globally would gain information that would assist them in motivating recommendations to the managers of the obstetric units with regard to consulting with advanced midwives by midwives in their obstetric units.

- Description: Scrutiny of the capabilities and accuracy of computer forensic tools is increasing as the number of incidents relying on digital evidence and the weight of that evidence increase. This thesis describes the capabilities of the leading proprietary and open source digital forensic tools. The capabilities of the tools were tested separately on digital media that had been formatted using Windows and Linux. Experiments were carried out with the intention of establishing whether the capabilities of open source computer forensics are similar to those of proprietary computer forensic tools, and whether these tools could complement one another. The tools were tested with regards to their capabilities to make and analyse digital forensic images in a forensically sound manner. The tests were carried out on each media type after deleting data from the media, and then repeated after formatting the media. The results of the experiments performed demonstrate that both proprietary and open source computer forensic tools have superior capabilities in different scenarios, and that the toolsets can be used to validate and complement one another. The implication of these findings is that investigators have an affordable means of validating their findings and are able to more effectively investigate digital media.

- Description: In trying to prove that derivations of type I AW -algebras are inner, I. Kaplansky introduced and developed the basics of the concept of Hilbert C- modules. He sought to generalize the idea of a Hilbert space by replacing the field C of all complex numbers with a general (commutative and unital) C-algebra. Twenty years later, the concept was broadened and expanded to non-commutative C-algebras by W. L. Paschke and M. A. Rieffel in their papers on inner product modules over B-algebras and induced representations of C-algebras, respectively. Since then, the theory of Hilbert C-modules has grown rapidly. It was used by G. G. Kasparov as the framework for his bivariant K-theory. More recently, Hilbert C-modules have formed the technical basis for the C*-algebraic approach to quantum group theory. The aim of this dissertation is to provide as detailed an account as possible of the theory of Hilbert C-modules, as given in a book of E. C. Lance, up to and including the KSGNS construction. The KSGNS construction, named after Kasparov, Stinespring, Gelfand, Naimark and Segal, is a generalization to Hilbert C-modules of the familiar GNS construction for C-algebras. The result by Kaplansky that all derivations of a type I AW-algebra are inner is given as an application in the final chapter of the dissertation.

Trends indicate that only iota of evidence implies that the concept of risk management is fully integrated and embraced as part of a culture for ensuring the successful project implementation by the Modern South African public sector organizations. Empirical research revealed that the common types of risks that have been affecting the successful implementation of government projects and programmes include: riots, fraud, corruption, changes in demographic figures, outsourcing risks, and floods and changes in weather. Most of the participants stated that risks associated with riots do not only arise from the riots within the government departments, but also in the external environment. In terms of the internal riots, they revealed that when the employees go on strike or riots on their own or in solidarity with the other trade unions, leading to the process for the implementation of government projects and programmes being affected. Yet, in certain cases, they noted that internal riots or strikes most occur as preceded by rumours that the riots by a particular union will take place and may significantly affect the ongoing process of implementation of government programmes. Besides risks associated with the internal riots by the employees and the communities, the interview findings also indicated that the other forms of risks arise from the strikes and riots by the private enterprises.

- Description: This research provides an historical, theoretical and practical appraisal of exogenous and endogenous money and money creation, with South Africa as the focus of the practical investigation. Monetary theory of recent decades can be categorised as belonging to one of two distinct paradigms: mainstream (neoclassical) or post Keynesian. The mainstream (orthodox) view presents a Euclidian or Cartesian, ergodic, deductive, and axiomatic theoretical interpretation of the world. This is perpetuated through the continued, and inaccurate, depiction in academia of exogenous money creation, the money multiplier concept, asset transformation by banks, imposed alterations to the money stock by central banks and long-run closed system equilibrium models (and associated homogeneity, and long term behavioural assumptions). In the real world, economic agents, structures, institutions and their interrelations are perpetually evolving. The post Keynesian paradigm provides the theoretical framework within which to understand such a world. Unfortunately the necessity for a multiplicity of methods and methodology makes it a paradigm that is currently prohibitively complex, preventing simple exposition. Money creation should, both historically, and according to the analysis conducted, be defined according to the actual source of change in the money stock, that is, credit extension. In a nonergodic world, changes in the stock of money take on a causal role with regard the initiation of productive processes, and thus influence future economic conditions. The simple, although powerful, technique of balance sheet analysis conducted herein provides a detailed method of identification of causal changes in money stock. Within the context of the institutional and structural environment, it clearly demonstrates the residual nature of money m modern economies. This research serves to emphasise the importance of monetary matters for economic management, as well as the important difference between the money creation process and the residual deposit securities. It serves also to discourage the perpetuation of fallacies of money creation, and capabilities of monetary authorities. In South Africa, as in most countries, the central bank can influence the conditions under which borrowers and banks mutually create money, but do not themselves create or distribute money beyond the facilitation of credit extension by banks
