- Description: Napping has been explored extensively as a means of counteracting the negative effects associated with shift work. A significant amount of this research has focused on the implementation of scheduled naps, with few studies considering flexible nap schemes. The current study therefore aimed to assess the effects of a flexible nap opportunity on the physiological, cognitive, performance, neurophysiological and subjective responses of a group of non shift workers over the course of a three-day simulated night shift regime. Additional foci were the effects of the nap condition on the extent of the circadian adaptation of the subjects to the irregular work schedule and the circadian-related influences associated with being awake during the night. 36 subjects – 18 males and 18 females – were recruited to participate in the current study. The data collection spanned twelve days, during which four, three-day long shift cycles were set up: three night shift cycles and one day shift cycle. During each night shift cycle, three separate experimental conditions were staggered, namely the nap condition, the no nap condition and a booster break condition (a collaborative study that completed the setup). The day shift served as a further comparison. Each cycle comprised of 12 subjects, which meant there were four subjects per condition during each cycle. The shifts were 8 hours in duration, with the no nap group following a standard break schedule evinced in industry. The three breaks taken during the shifts amounted to a total time of 1 hour. The nap group was afforded a 1 hour flexible nap opportunity between 00h00 and 03h00 with no other breaks. Therefore, both conditions had the same amount of work time. During the shifts, subjects performed two simple, low arousal tasks (beading and packing) and completed a test battery roughly every two hours which was comprised of physiological, performance, neurophysiological and subjective measures. It was found that the inclusion of the nap opportunity significantly improved output performance and response time during a low precision, modified Fitts tapping task over the course of three night shifts, relative to no napping. Physiologically, napping resulted in higher heart rate frequency measures by the end of the shifts, which were also accompanied by significant reductions in subjective sleepiness ratings during all iii the night shifts. The nap group’s responses in this case, did not differ significantly from those of the day shift. Both simple reaction time and memory performances improved as a result of the nap inclusion, but only during the third night shift. The majority of the measures included in the research also depicted the effects of the circadian rhythm, which was indicative of the pronounced effect that this natural biological down regulation has on performance during the night. Napping reduced the severity of these effects during beading performance and measures of subjective sleepiness. With regard to habituation, the nap opportunity also resulted in positive changes in the responses of beading performance, high precision response time, simple reaction time and both subjective sleepiness measures, relative to no napping. Sleep diary responses indicated that although sleep length and quality during the day were significantly reduced for both night-time conditions, recovery sleep (length and quality) for the nap group did not differ significantly from the no nap group. The findings of this research indicate that the inclusion of a flexible napping opportunity during the night shift had positive effects on some physiological, performance and subjective responses, and that this intervention is as beneficial as scheduled napping. Specifically, napping resulted in a significantly higher output during the beading task, relative to the no nap group despite the duration of work time being the same. As such the introduction of a flexible, self-selected nap opportunity is a practical, effective and individual-specific means of alleviating the negative effects of shift work, while improving certain performance parameters. Therefore, industries should consider its inclusion in their fatigue management programs. However, contextspecific considerations must be made, with regard work scheduling, individual differences and task demands when implementing such an intervention. This will ensure that its introduction will be well received and in time, lessen the health and work-related decrements associated with shift work.

- Description: Economical and educational problems are caused by the reversed effect of the Employment Equity Act and Affirmative Action. One such problem is called “brain drain” (Lundy, 2006), The general aim of the research was to determine whether affirmative action caused final year students of the Nelson Mandela Metropolitan University to consider overseas employment. A literature study was conducted before the empirical objectives were reached. The empirical study was of a quantitative descriptive and inferential nature. A cross-sectional survey design was used to achieve the empirical objectives. A self- administered survey package was handed out to final year students within the various disciplines at their various classes. One hypothesis was tested. The results indicated that support was found for the hypothesis. The findings are discussed in relation to the data gathered. The implications of the research and the limitations of the study are outlined in the Results chapter.

- 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: Purpose – The primary aim of the study was to establish to what extent company vision impacted on productivity, profitability, morale and the quality of product at Borbet SA. Borbet SA is an aluminium wheel manufacturer situated in Port Elizabeth, Eastern Cape, South Africa. The secondary aim of the study was to establish whether the vision would be reached by applying the company values in action at Borbet SA. Methodology – Seventy-seven respondents employed at Borbet SA completed a Likert Scale Questionnaire to measure their knowledge and application of the company vision and values. The research study made use of a combination of qualitative and quantitative research approaches. The research study was qualitative as the topic was subjective to perception of the participants. However, the data was to be analyzed quantitatively through statistical practices. Findings – Overall, the participants were 99 percent aware of the vision statement at Borbet SA. Therefore, Borbet SA had succeeded in making company vision a part of their business strategy. The successful implementation of a vision and values at Borbet SA have improved productivity, profitability, morale and quality of product at the company. The study’s main findings were that employees between the ages of 18 – 29 years were especially optimistic of the company vision and values. Employees working at Borbet SA for between 4 – 5 years and working at Borbet for between 0 – 3 years tended to be more unenthusiastic about company vision and values. Middle management, including supervisors and team leaders, were also pessimistic about certain aspects concerning the vision of the company. Research limitations – One of the limitations of the research were that only 77 of the workforce completed the voluntary questionnaire. The questionnaire was in English and this was not the first language of the majority of the employees at Borbet SA. This could have prevented them from completing the questionnaire because they might not have felt confident in responding in ii English. Educational levels could also have influenced the response to the questionnaire seeing that not all employees had the same educational levels and, thus, this could have been intimidating. Recommendations – The main recommendation was that a mentoring programme be implemented in which younger and older employees could motivate each other and build morale. The management of Borbet SA was recommended to have team building sessions with middle management, supervisors and team leaders to build morale and optimism in these groups. Employees working for 4 – 5 years needed to be evaluated and motivated as some of them could have felt stagnant in their job positions.

- Description: The purpose of this treatise is to ascertain the impact of economic downturn on Black Economic Empowerment (BEE) and Banks. This has been sparked by the huge speculations in the market as to what will happen to BEE and how will the banks cope in general with the impact of this scourge. It is imperative to understand the influence of the 2008+ economic downturn on socio-economic reconstruction and development in South Africa and the black economic empowerment and its funding mechanisms. The treatise has two phases the, namely the theoretical phase and a bit of narrative phase. In the theoretical phase the research study interrogates what the literature review reveals about the economic downturn, BEE as well as performances of different banks across the world. This shows the economic impact that the banks have had to endure during the economic downturn. This resulted in stock markets losing their value. The dividend earners were significantly affected including a sizeable number of BEE companies. The BEE companies are perceived to be too reliant on debt on to finance their deals and this treatise will look at various options of financing a BEE deal and what is deem to the most suited financing structure. The narrative phase involves semi-structured interviews that were conducted in order to ascertain the real impact that South African were faced with and how they have managed to steer clear of the turbulent waters. This also looked at how the BEE consultant views the current occurrences in the market.

- Description: Introduction: Adherence to Highly Active Antiretroviral Therapy (HAART) is critical for optimal therapeutic outcomes. A possible factor in adherence is the impact of HAART on sexual functioning. Methods: A mixed methods approach was used. A cohort of 14 people living with HIV/AIDS (PLWHA) in Grahamstown was identified. Two semi-structured interviews and two structured questionnaires were administered. In-depth interviews were conducted with two HIV counsellors in so as to obtain a different perspective on the topics. The theoretical framework used three health behaviour models: the Health Belief Model, Leventhal‘s Common-Sense Model of self regulation and the Transtheoretical model. Results: The participants were between 27 and 49 years old and had been on HAART for between 9 months and 10 years. Six participants were support staff members from Rhodes University and eight from the Raphael Centre – a local NGO which assists PLWHA.In most of the participants HAART was associated with increased libido and improved sexual functioning (sexual activity and sexual enjoyment). The use of alcohol increased risky sexual behaviour. Issues of adherence were seemingly not directly affected by the effects of HAART on sexuality. PLWHA, especially women, face challenges related to their sexuality, some of which are not directly related to their illness and treatment. The fear of transmitting drug resistant HIV or getting re-infected, stigma, disclosure issues,difficulties negotiating for safe sex among women, HAART-related lipodystrophic changes that affect one‘s sense of self and unmet reproductive needs are some of the problems that were reported. The men‘s dislike for condoms was overt and blatant. Discussion: Being diagnosed with HIV and reaching a point where treatment is requiredare life-changing events. Making decisions about one‘s life (including adherence to HAART, alcohol use and knowingly partaking in risky sexual encounters) become all the more significant in the context of AIDS. Intentional non-adherence is informed by the individual‘s assessment of the costs and benefits of taking treatment. Cultural influences,gendered power relations and misconceptions strongly influence sexual behaviours. Conclusion: The general lack of attention among health care providers concerning issues related to PLWHA‘s sexuality and reproductive issues needs to be addressed. Insights fromthe theoretical models should be integrated with empirical findings in designing adherence interventions.

- Description: Introduction: Adherence to Highly Active Antiretroviral Therapy (HAART) is critical for optimal therapeutic outcomes. A possible factor in adherence is the impact of HAART on sexual functioning. Methods: A mixed methods approach was used. A cohort of 14 people living with HIV/AIDS (PLWHA) in Grahamstown was identified. Two semi-structured interviews and two structured questionnaires were administered. In-depth interviews were conducted with two HIV counsellors in so as to obtain a different perspective on the topics. The theoretical framework used three health behaviour models: the Health Belief Model, Leventhal‘s Common-Sense Model of self regulation and the Transtheoretical model. Results: The participants were between 27 and 49 years old and had been on HAART for between 9 months and 10 years. Six participants were support staff members from Rhodes University and eight from the Raphael Centre – a local NGO which assists PLWHA.In most of the participants HAART was associated with increased libido and improved sexual functioning (sexual activity and sexual enjoyment). The use of alcohol increased risky sexual behaviour. Issues of adherence were seemingly not directly affected by the effects of HAART on sexuality. PLWHA, especially women, face challenges related to their sexuality, some of which are not directly related to their illness and treatment. The fear of transmitting drug resistant HIV or getting re-infected, stigma, disclosure issues,difficulties negotiating for safe sex among women, HAART-related lipodystrophic changes that affect one‘s sense of self and unmet reproductive needs are some of the problems that were reported. The men‘s dislike for condoms was overt and blatant. Discussion: Being diagnosed with HIV and reaching a point where treatment is requiredare life-changing events. Making decisions about one‘s life (including adherence to HAART, alcohol use and knowingly partaking in risky sexual encounters) become all the more significant in the context of AIDS. Intentional non-adherence is informed by the individual‘s assessment of the costs and benefits of taking treatment. Cultural influences,gendered power relations and misconceptions strongly influence sexual behaviours. Conclusion: The general lack of attention among health care providers concerning issues related to PLWHA‘s sexuality and reproductive issues needs to be addressed. Insights fromthe theoretical models should be integrated with empirical findings in designing adherence interventions.

- 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: South African electricity tariffs were relatively low compared to the rest of the world. The average South African business has for long taken this advantage for granted and is now surprised to realise that electricity is becoming an expensive and scarce commodity. The South African electricity supply industry is far more complex than the average person may think. The infrastructure supporting this industry is extremely costly; takes long to develop and build and requires careful planning and management. There are many sources of energy and many technologies for generating electricity. However, many of these do not appear quite ready to serve the needs of the industry. The manufacturing industry depends heavily on electricity. The recent power outages and tariff increases have served as a cruel reminder of this fact. The automotive sector has lost many days of production and the increasing electricity costs erode the profitability of the affected companies. The automotive suppliers and vehicle manufacturers have expressed their concerns. Indications are that some have reduced the number of employees and may even face bankruptcy. This research aims to gain the perspective of senior managers in the automotive industry regarding the impact of the increased electricity tariffs on their manufacturing costs. Naturally, all electricity consumers will be affected by this. However, this research aims to investigate the significance of the effect on the automotive industry as well as obtain some indication of which factors determine the level of dependency. Each company has to react strategically to the situation and apply those measures which are available to them. This research determines how strongly the industry feels about reacting and which strategic measures they will apply. The outcome is descriptive of the circumstances in the industry and indisputably serves as an indication of the financial impact of electricity tariff increases.

- Description: This project aimed at assessing and evaluating the extent to which deployed ICTs in the rural area of Dwesa have impacted on the lives of the residents there. This occurred between February 2008 and December 2009. The ICTs are an initiative collaboration of University of Fort Hare and Rhodes University, sponsored by Telkom SA, the Government of Finland and other market players. This research started by reviewing the extent to which rural areas in general have lagged behind in terms of accessing ICTs, paying closer attention to governmental policies and initiatives towards rural development. The project then looked at the currently available ICTs in Dwesa and trying to measure the extent to which they have been useful or rather complicated the lives of the people there. Also important was a review of the efforts made by the technology innovators towards ensuring that relevant and appropriate technologies were made available to the rural people. The project also looked into issues of sustainability, maintenance and general running of the project to ensure its success. Important key findings on access, appropriateness of ICTs, use and knowledge about the ICTs, literacy levels, education standards and readiness of community to use ICTs were made during this research. Also included in the findings are issues on state of infrastructure, already present services, and current uses of ICTs as well as notable positive ICT impact in Dwesa. The most important findings of this research were to assist in providing a detailed prediction of future impact of various possible new technologies that can be introduced to Dwesa. This research also had to be able to bring out a monitoring and evaluation system that should measure the impact of the ICT interventions over the past 5 years. This project was initiated in 2005 and is identified by the name Siyakhula Living Lab. The concept of a living lab is a new term for providing ICTs in an area where their usefulness can be tested based on the natural environment in which they are being used.

The impact of the Western conceptualization of the Christian gospel on its communication in a non-Western environment, with particular reference to the AmaXhosa

- Description: This thesis examines the extent and nature of the impact of the contextualization of Christianity upon the amaXhosa from the missionary irruption in the nineteenth century to the present day, and proceeds to examine the implications of this impact for the presentation of the Christian gospel in the contemporary Eastern Cape. Chapter One describes the problem, offers definitions of key concepts and outlines the procedural method for the rest of the thesis. Chapter Two deals with the question of the cross-cultural communication of the Christian gospel in theory. Doctrinal questions such as the nature of the gospel are examined. The basic hermeneutical issue of the categorization of doctrinal tenets according to whether they are required or simply permitted is discussed in terms of Osborne's categories: 'cardinal', 'non-cardinal'. Tenets which are found to be 'anti-scriptural' would be rejected. Specific hermeneutical topics such as language and meaning, symbolics, textuality and orality are then discussed. This is followed by a survey of secular influences which affect a conceptualization. This chapter is preparatory to, and definitive for, the discourse which follows. Chapter Three outlines the cultural heritage from which the Western missionary contextualization of Christianity developed. It shows the extent to which this presentation of the gospel was dependent upon the philosophy which Britain and Europe inherited from the classical Greek culture. More modern developments such as the Enlightenment, Empiricism and Historicism bring the discourse up to the point at which the missionaries arrived. Chapter Four deals with the initial encounter between the missionaries and the amaXhosa. A brief account is given of the nature of the religious and spiritual aspects of the Xhosa culture which first encountered Christianity. The doctrinal section of this chapter deals with those doctrines in the missionary message which became issues for the amaXhosa. The hermeneutical section shows how the cultural setting of the West (vii) affected both the contextualization by the missionaries and the conceptualization by the amaXhosa. To a large extent, the missionaries made the double mistake of imposing their culture on the amaXhosa and failing to accord respect, even recognition, to the Xhosa culture. This amounted to imperialism, which, together with the political imperialism of Britain as the colonizing power, evoked responses from the Xhosa community which are outlined in section 4.4, including those of Nxele and Ntsikana. Because the impact of the Western contextualization is an on-going phenomenon, the thesis continues to trace its development up to the present time. Apartheid is briefly mentioned in Chapter Five. The point is made that all white people were perceived by the amaXhosa to be Christians, and the architects and practitioners of apartheid claimed to be Christians. This ideology therefore had a direct effect on the Xhosa conceptualization of the gospel. The architects of apartheid actually believed that they were accepting God's gift and mandate. This chapter includes Black theological reaction to apartheid in terms of the South African version of Liberation theology. Chapter Six returns to Western Theology in order to bring the sphere of discourse from the point at which it left off at the end of Chapter Three up to the present time. The schools of thought in this period are: Secularism and Existentialism, together with their theological extension, Demythologization. The main religious movements are the Charismatic Movement and Neo-Pentecostalism. Postmodernism came as a later philosophical school, to be followed by Globality. Chapter Seven deals with black South African reactive and proactive responses. The predominant theologies are those of Dwane, Buthelezi, Boesak and Mtuze. Although Dwane, Buthelezi and Boesak came on the scene at the same time as the black theologians reviewed in Chapter Five, their work is placed here because it differs significantly from the more radical responses of the latter. Mtuze is post-apartheid, and responds to the developments outlined in Chapter Six. Chapter Eight draws the findings of the thesis together, by considering how the Christian Gospel ought to be presented to the various contemporary sub-cultures of the amaXhosa. (viii) The last Chapter applies the findings of the thesis to the task in hand. The desired outcomes are listed and briefly discussed. The task ahead is enunciated in terms of manpower and other resources for the effective communication of the Christian gospel in the twenty-first century. The past, present and projected programmes of the Bible Institute Eastern Cape [the target institution] are described and assessed. Finally, topics which presented themselves in the course of the preparation of this thesis are suggested for future research.

- Description: This study examines the experiences of the school management teams and educators of the Isibane Circuit in the Queenstown District, regarding the implementation of an Integrated Quality Management System (IQMS) policy at school level. Following an agreement reached in 2003 between the South African Education Department and the major teacher organisations in this country, the IQMS was scheduled to be implemented in public schools from 2004. Two major challenges are identified and explained: accountability and development of human resources, as well as contradictions between internal and external evaluations. The study also elaborates on the changes in the educational history from the apartheid system to the democratic system of education. Nine schools participated in the study (two secondary schools and seven primary schools). These schools were purposely selected due to the fact that they had started implementing the IQMS policy, which was the main criterion for selection. Semi-structured interviews were used to gather data from principals, Heads of Departments as well as post-level one educators concerning their experiences of the IQMS implementation. The findings indicated that while the IQMS policy was good on paper, it was extremely difficult to implement. Issues of honesty and trust were at the root of difficulties that made the IQMS implementation challenging. The participants‟ understanding of IQMS was that it was intended for the provision of quality education and development.

- Description: Globally, the automotive industry has progressed through various stages of manufacturing paradigms over many decades. The automotive industry is one of South Africa's most important sectors, with many of the major automotive multinationals using South Africa to source components and assemble vehicles for both the local and international markets. Lean production has been recognised as the most effective manufacturing strategy that generates high quality products at low costs, while still producing different varieties of products. The effectiveness of the lean production lies in the relationships that exist between the original equipment manufacturer and its suppliers. Klopping and McKinney (2004) state that the evolution of the Internet as a business tool enhanced by the development of the World Wide Web has led to the emergence of the fast growing e-commerce applications. This quantitative research study aims at investigating the e-business relationships that exist between a selected Eastern Cape Original Equipment Manufacturer and its first tier suppliers. The primary objective of the study was to obtain and document direct feedback from the South African Automotive Manufacturing Industry about their perceptions, opinions, plans and activities in respect to Business to Business Electronic Commerce - called "e-Business" for the remainder of this study. The study shows that most automotive suppliers are comparatively heavy users of e-business. Many of these suppliers are also using e-mail and have a website, but comparatively few engage in more complex e-business operations. The greater majority of respondents reported that e-business has facilitated efficiency of their operations. However, e-business is not being utilised effectively between the OEM and its suppliers even with the introduction of Covisint which is a common e-business interface that was created through collaboration between major OEMs and their suppliers to ease e-business in the automotive industry.

- Description: The utilisation of estuary headwater environments by young estuary- and marine-spawned fish species was investigated together with the effects of riverflow alteration, in-stream barrier effects and non-native ichthyofauna on the nursery function of these habitats. The distribution and abundance of young estuary- and marine-spawned fish were sampled using seine and fyke nets in the headwater environments of four permanently open Eastern Cape systems, namely the Great Fish, Kowie, Kariega and Sundays Estuaries. Within the suite of study systems, the first of two case studies focussed on barrier effects of in-stream structures on fish migration. This was undertaken in the Sundays River. In the second case study, predation and competition dynamics of the non-native piscivorous Micropterus salmoides on estuary-dependent fish was investigated in the estuary headwater regions of the Kowie River system. In all four estuaries, young estuary-spawned fish species dominated the ichthyofaunal community followed by marine-spawned species, despite varied freshwater inflow resulting in headwaters varying in salinity from fresh to hypersaline. Fish community structure however, differed largely between estuaries, with both freshwater abstraction and unnatural elevation of freshwater into estuaries, as a result of inter-basin transfers, affecting these communities. In-stream structures were found to effect upstream movement of fish in two ways, dependent on the type of barrier. Partial (size-dependent) and complete (species-dependent) restriction to upstream migration of fish by causeway-type instream structures were observed. Weir-type in-stream structures acted as a complete barrier to most species, regardless of fish size. Predation of estuary- and marine-spawned fish species by large sized M. salmoides was recorded, although these fish did not contribute significantly to their diet during this study. However, the main dietary components found in smaller sized M. salmoides stomachs overlap with those of juvenile estuary- and marinespawned fish species, suggesting feeding competition between the juveniles of indigenous and non-native fish species.

- Description: The African potato is used as an African traditional medicine for its nutritional and medicinal properties. Most research has been carried out on H. hemerocallidea, with very little or nothing on other Hypoxis spp. The main aim of this project was to provide scientific data on the anticancer, anti-inflammatory and antioxidant properties of H. hemerocallidea, H. stellipilis and H. sobolifera chloroform extracts and their active compounds. The hypoxoside and phytosterol contents of the three Hypoxis spp. were determined using TLC, HPLC and GC. H. hemerocallidea and H. sobolifera chloroform extracts contained the highest amounts of hypoxoside and β-sitosterol, respectively. For the anticancer properties, cytotoxicity of the Hypoxis extracts and its purified compounds were determined against the HeLa, HT-29 and MCF-7 cancer cell lines (using MTT), and PBMCs (using CellTiter-Blue®). H. sobolifera had the best cytotoxicity against the three cancer cell lines, whereas H. stellipilis stimulated HeLa and HT-29 cancer cell growth. IC50 values of hypoxoside and rooperol were determined. DNA cell cycle arrest (using PI staining) occurred in the late G1/early S (confirmed by increased p21Waf1/Cip1 expression) and G2/M phases after 15 and 48 hrs, respectively, when treated with Hypoxis extracts and rooperol. H. sobolifera and rooperol activated caspase-3 and -7 (using fluorescently labelled antibodies) in HeLa and HT-29 cancer cells, and caspase-7 in MCF-7 cancer cells after 48 hrs. Annexin V binding to phosphatidylserines in rooperol treated U937 cells confirmed early apoptosis after 15 hrs. The TUNEL assay showed DNA fragmentation in the three cancer cell lines when treated with H. sobolifera and rooperol for 48 hrs. A shift pass the G2/M phase has led to the investigation of endoreduplication, which was confirmed by cell/nucleus size, and anti-apoptotic proteins (Akt, phospho-Akt, phospho-Bcl-2 and p21Waf1/Cip1). U937 cell differentiation to monocyte-macrophages was optimized using PMA and 1,25(OH)2D3, which was confirmed by morphological and biochemical changes. For the anti-inflammatory properties, Hypoxis extracts and rooperol significantly increased NO production in monocyte-macrophages (pre-loaded with DAF-2 DA) and phagocytosis of pHrodoTM E. coli BioParticles®. The treatments had no effect on COX-2 expression in monocyte-macrophages. The phytosterols significantly increased IL-1β and IL-6 secretion xv (using the FlowCytomix Multiplex human Th1/Th2 10plex Kit I) in the PBMCs of one donor. For the antioxidant properties, Hypoxis extracts and rooperol significantly increased ROS production in undifferentiated and differentiated U937 cells, which were pre-loaded with DCFH-DA. Hypoxis extracts and purified compounds had ferric reducing activities, but only rooperol had ferric reducing activities significantly greater than ascorbic acid. β-sitosterol, campesterol and cholesterol significantly increased SOD activity in Chang liver cells, while H. stellipilis, H. sobolifera and rooperol decreased SOD activity. Anticancer, anti-inflammatory and antioxidant properties of the Hypoxis extracts may be attributed to the β-sitosterol content, because Hypoxis chloroform extracts contained very little or no hypoxoside. Unidentified compounds, and synergistic and additive effects of the compounds may have contributed to the biological effects. This study confirms previous reports that rooperol is the active compound. Results provide scientific data on the medicinal properties of one of the most frequently used medicinal plants in South Africa.

- Description: The invasion of Acacia mearnsii in the Kouga catchment, Eastern Cape, South Africa, has various negative impacts on the ecosystem. These impacts include: reduced species richness, increased water use, increased nutrients and increased N cycling rates. The native shrubby fynbos vegetation has adapted to the acidic nutrient poor soils and Mediterranean climate of the Kouga Mountains. Fynbos, however, is currently being out competed by the much taller Acacia mearnsii trees, due to their competitive nature and ability to fix nitrogen, thereby enriching the soil. The invaded sections of the valley bottoms and lower hill slopes are characterised by an almost complete monoculture of Acacia mearnsii, with very few fynbos species still present. The Department of Water and Environmental Affairs sponsored Working for Water programme started clearing Acacia mearnsii in 1996 in the Kouga Mountains. Cleared sites have remained bare for long periods, indicating that soil properties are not favourable for indigenous propagule re-establishment. The aim of this research was to assess how A. mearnsii invasion and clearing affect fynbos recovery through its impact on soils. This was done by characterising vegetation and soil properties on fynbos, infested and cleared slopes. Vegetation cover for various growth forms was determined and a species list was compiled for each plot. The slope angle, surface hardness, litter cover, bare ground cover and soil depth were measured in the field, whereas water repellency, particle size and the chemical composition were measured in the laboratory. Furthermore, the plant establishment capacity of soils from fynbos, infested and cleared slopes was calculated. This was done by germinating fynbos seeds and growing fynbos plants in soils from the various slopes. The effect that invasion and clearing has on soil erosion was quantified using erosion plots on fynbos, infested and cleared slopes. The invasion and clearing of Acacia mearnsii led to an increase in soil nutrients, especially nitrogen, phosphorus, potassium, carbon and manganese. Furthermore, soils became more acidic, with increased water repellency and reduced surface hardness. The vegetation changed to a tree-dominated structure, replacing the native species. Native plant germination was relatively unaffected by invasion and clearing, with an increase in germination just after clearing. Plant growth of a native grass, Themeda triandra, and herb, Helichrysum umbraculigerum, has increased on soils from cleared slopes. This study showed that soil movement increased on slopes which are invaded and cleared of Acacia mearnsii, with erosion rates doubling on invaded slopes

- Description: In South Africa, the trend has been towards the decentralising of authority and giving greater powers to schools. This implies the active involvement of the school governing body members, the school management team members and the Level One educators in the day-to-day functioning of the school. Whilst some schools have welcomed this change and seen this devolution of power as an added advantage contributing to the efficacy of schools, some schools have struggled, while others have failed dismally to cope with this added responsibility of managing their own resources. The researcher, being an educator involved in this transition, has been intrigued by the success of some self-managing schools and the failure of others. The following words of Oliver Wendell Holmes have inspired the investigator to conduct this research to ascertain the reasons for the success of certain schools and the failure of others: “What lies behind us and what lies before us are tiny matters compared to what lies within us.” Since the performance of schools is normally ranked according to their matriculation pass rates, this research focused on six self-managing schools in the Port Elizabeth District. These schools were selected on the basis of their matriculation performances in 2008. Two of the schools had achieved an above 85 percent matriculation pass rate (Category A); two obtained a 50 percent pass rate (Category B); while the other two schools obtained matriculation pass rates of between 25 percent and 30 percent (Category C). Although the research relied strongly on a qualitative method of inquiry, because of the nature of the data and the need to obtain a better understanding of the feelings, attitude and perceptions of those in management positions, governing body positions and members of the personnel, multiple instruments for data collection such as a literature review and the study of school documents and questionnaires, were used. This inclusion of these multiple instruments for obtaining information, which is also called triangulation, contributed to the reliability and validity of the empirical investigation. Although the data was presented in the form of tables and graphs, vi which alludes to a quantitative approach, a narrative interpretation of the findings, which is associated with a qualitative method of inquiry, was also presented. An analysis of the findings revealed that there was a great amount of involvement of the principals, school management team members and Level One educators in Category A schools, which had a matriculation pass rate of above 85%, in the following change management strategies: the establishment of a vision, planning and organising, teamwork, training and development, communication, praise and incentives, and evaluation and feedback. There was also a great contribution by the school governing body members. However, the study revealed that Category B and Category C schools did not effectively use communication, praise and incentives and evaluation and feedback as change management strategies. It was evident from the empirical investigation that in Category B and C schools, the school governing body members were less, or not involved in the usage of the change management strategies applied. According to the results based on the six-facet model of Emotional Intelligence, Category A schools obtained 80% and above in the competencies relating to the self and social domain. Category B schools fluctuated between 50 percent and 80 percent in both dimensions, while Category C schools fluctuated between 30 percent and 80 percent. The findings suggest that there should be greater involvement of all stakeholders, especially the school governing body members, in the establishment of a vision, planning and organising, communication, teamwork, training and development, praise and incentives and the provision of feedback and evaluation for self-managing schools to become effective and improve their performances. Professional development, especially in the areas pertaining to Emotional Intelligence competencies such as personal and interpersonal skills, should be prioritised. This thesis proposes that, on the basis of the investigation carried out at the six participating schools on the influence of Emotional Intelligence on the change management strategies adopted in self-managing schools, schools use strategies such as the establishment of a vision, planning and organising, communication, teamwork, training and development, praise and incentives and evaluation and feedback to ameliorate the damaging impact of change. There should be continuous training and development at schools, especially for the school governing body members, who are elected every three years. The newly elected school governing body members need to develop the necessary skills to effectively contribute to the efficacy of schools. The human resource is the vital ingredient in schools, thus for any progression or improvement, all stakeholders need to be informed, trained and enriched. Since Emotional Intelligence can be learned, professional development in the area of Emotional Intelligence should be given more thought and included in training courses, focusing on the development of personal and interpersonal skills. The Emotional Intelligence training should be conducted as part of teacher training courses as well as on an annual basis for educators already in the teaching system, since Emotional Intelligence can influence the use of change management strategies at schools and enhance the efficacy of the functioning of self-managing schools.

- Description: A review of the academic literature related to “strategic leadership” reveals that the performance of an organization will indeed be influenced by the application of this phenomenon. This thesis confines its research to a case study on Ellerine Holdings Limited, a multi-billion rand enterprise that trades in the competitive Southern African furniture retail industry. Following the 2007 acquisition of Ellerine Holdings Limited (EHL) by African Bank Investments Limited (ABIL), a new Chief Executive Officer (CEO) was appointed to develop and to lead the strategic changes that were envisioned for EHL. The research examines how the performance of EHL has been influenced since the appointment of Toni Fourie as the new CEO in February 2008. Boasting a reputation borne from his previous successes in organizational transformation, Fourie was ABIL’s first-choice leader for this challenge. Fourie displays qualities, attributes, behaviours and traits that are characterized by the phenomenon of “strategic leadership”. He has been the focus of media attention for the aggressive strategic changes that he has introduced within the organization. A quantitative analysis of EHL’s financial performance (between 2007 and 2009) indicated that there was a constant decline in the organization’s PBT (Profit Before Taxation) during the period observed. However, the research determined that turbulent conditions in the macro-economic environment (such as the global economic recession in 2008 and 2009) complemented by mitigating micro-economic factors, would have adversely skewed the conclusions in this document if the research was limited to quantitative analysis alone. Hence, the researcher explored a qualitative research framework by collecting and assimilating data from available documentation, and from formal interviews that were conducted with research participants representing the organization’s new leadership. These participants included the new CEO, Fourie, and the new Director of Strategy, Dr. Louis Carstens. Information was also obtained from informal discussions that were conducted with other senior executives, and with an ex general manager of one of EHL’s business units, who was based in the Eastern Cape region at the time. An examination of all of this data concluded that although Ellerine Holdings Limited was not achieving all of its financialperformance objectives, there was general consensus that the CEO’s strategic choices would yield the desired financial results from the mediumterm (namely, year-03 of his tenure) onwards. The CEO’s optimism and conviction that his strategic interventions will address long-term financial sustainability is shared by both EHL’s internal and external stakeholders. It emerged that EHL’s stakeholders were satisfied with the accelerated progress reflected in the organization’s non-financial performance indices. These indicators included the sowing of a new organizational culture; improved cost-base efficiencies; labour productivity; customer satisfaction; employee empowerment; innovation and creative thinking; collaborative and participative engagement; structural rationalization, and the introduction of new processes and procedures. The research from the EHL case study concluded that the phenomenon of strategic leadership can have a positive influence on various qualitative indicators within an organization. The research also determined that despite unforeseen conditions in both the macro and micro economic environments, an effective strategic leadership will remain committed to its vision, and resilient to its critics and competitors. This research further concludes that successful organizational transformation (within a macro enterprise) is ostensibly dependent on the interventions of a strategic leader who displays a specialist set of skills and behaviours. These strategic leaders have the ability to successfully shift the cognitive paradigms of their employees, thereby creating an enabling environment for the implementation of their strategic choices.

- Description: A review of the academic literature related to “strategic leadership” reveals that the performance of an organization will indeed be influenced by the application of this phenomenon. This thesis confines its research to a case study on Ellerine Holdings Limited, a multi-billion rand enterprise that trades in the competitive Southern African furniture retail industry. Following the 2007 acquisition of Ellerine Holdings Limited (EHL) by African Bank Investments Limited (ABIL), a new Chief Executive Officer (CEO) was appointed to develop and to lead the strategic changes that were envisioned for EHL. The research examines how the performance of EHL has been influenced since the appointment of Toni Fourie as the new CEO in February 2008. Boasting a reputation borne from his previous successes in organizational transformation, Fourie was ABIL’s first-choice leader for this challenge. Fourie displays qualities, attributes, behaviours and traits that are characterized by the phenomenon of “strategic leadership”. He has been the focus of media attention for the aggressive strategic changes that he has introduced within the organization. A quantitative analysis of EHL’s financial performance (between 2007 and 2009) indicated that there was a constant decline in the organization’s PBT (Profit Before Taxation) during the period observed. However, the research determined that turbulent conditions in the macro-economic environment (such as the global economic recession in 2008 and 2009) complemented by mitigating micro-economic factors, would have adversely skewed the conclusions in this document if the research was limited to quantitative analysis alone. Hence, the researcher explored a qualitative research framework by collecting and assimilating data from available documentation, and from formal interviews that were conducted with research participants representing the organization’s new leadership. These participants included the new CEO, Fourie, and the new Director of Strategy, Dr. Louis Carstens. Information was also obtained from informal discussions that were conducted with other senior executives, and with an ex general manager of one of EHL’s business units, who was based in the Eastern Cape region at the time. An examination of all of this data concluded that although Ellerine Holdings Limited was not achieving all of its financialperformance objectives, there was general consensus that the CEO’s strategic choices would yield the desired financial results from the mediumterm (namely, year-03 of his tenure) onwards. The CEO’s optimism and conviction that his strategic interventions will address long-term financial sustainability is shared by both EHL’s internal and external stakeholders. It emerged that EHL’s stakeholders were satisfied with the accelerated progress reflected in the organization’s non-financial performance indices. These indicators included the sowing of a new organizational culture; improved cost-base efficiencies; labour productivity; customer satisfaction; employee empowerment; innovation and creative thinking; collaborative and participative engagement; structural rationalization, and the introduction of new processes and procedures. The research from the EHL case study concluded that the phenomenon of strategic leadership can have a positive influence on various qualitative indicators within an organization. The research also determined that despite unforeseen conditions in both the macro and micro economic environments, an effective strategic leadership will remain committed to its vision, and resilient to its critics and competitors. This research further concludes that successful organizational transformation (within a macro enterprise) is ostensibly dependent on the interventions of a strategic leader who displays a specialist set of skills and behaviours. These strategic leaders have the ability to successfully shift the cognitive paradigms of their employees, thereby creating an enabling environment for the implementation of their strategic choices.

- Description: Research indicates that effective talent management is essential in achieving organisational excellence and is a driving force for business success. This study focused on investigating VWSA Group Service division’s employee talent management process as seen or perceived by employees. The employee attitude and understanding of the 2010 strategy was also evaluated. In achieving this objective a literature review on talent management was conducted and questions formulated which formed part of the survey. The questionnaire was self-administered and sent to the stratified random sample of individuals who were eligible for survey. The main findings of this research are that the 2010 strategy was well received by the employees and that seventy seven percent of the respondents who took part in the study do understand the 2010 strategy and what it is all about. The study also highlighted that employees believe Project 1 in the 2010 strategy will be achieved. Employees were uncertain that compensation and leadership style are variables that influence or promote talent management. From the literature review it is explained that in order for talent management to be effective it must be aligned to organisational strategy. Various recommendations were made, for example conducting of skills gap analysis with a view to identify skills employees need to possess in order to meet the objectives of the 2010 strategy. Another recommendation was the formation of talent pools from which to recruit high talented staff and whose skills will be required to meet the objectives of the organisational strategy. A final point emanating from the study, is that when it comes to talent management and achieving organisational strategy it is not business as usual. Companies need to be aware of brand profiles most desired by highly talented individuals; they also need to be aware of various recruiting strategies as well as acknowledge that different employees are at different levels of the motivational hierarchy.

- Description: This study was motivated by the need to improve curriculum relevance in poor rural schools through contextualised teaching and learning based on the management of local natural resources. It involved four schools which are located in the Ngqunshwa Local Municipality of the Eastern Cape Province of South Africa. The study's aim was to provide insight into and better understanding of the curriculum implementation process regarding natural resource management (NRM) education in a poor rural education context. This was done by analysing the extent of NRM integration in pedagogic texts, activities and practices in the different fields which constitute the structure of the pedagogic system in this education sector. The study adopted an interpretivist approach to the analysis, which was based on indicators of the extent of NRM integration, and was informed by Bernstein's concepts of classification and curriculum recontextualisation, and his model of the structure of the pedagogic system. The items which were analysed included national and provincial Grade 10 Life Sciences curriculum documents, Grade 10 Life Sciences textbooks, in-service training workshops for Life Sciences teachers, and various school documents, activities and practices. The analysis also involved interviews with educators, and classroom observations of Grade 10 Life Sciences lessons. The results revealed a very high overall level of NRM integration in the Grade 10 Life Sciences curriculum documents produced at national and provincial levels. The overall level of NRM integration was also found to be very high in the Grade 10 Life Science textbooks that were analysed, but very low in the in-service teacher training workshops, and in the schools' documents, activities and practices, especially in the Grade 10 Life Sciences lessons, and in schools' end-of-year Grade 10 Life Sciences examination papers. The study makes a number of recommendations towards effective integration of NRM into the curriculum of Eastern Cape's rural poor schools which include more specific and explicit reference to NRM in the official Grade 10 Life Sciences curriculum documents, the provision of environmental education courses to district education staff and Grade 10 Life Sciences teachers, the training of teachers in the classroom use of textbooks and other educational materials, and regular monitoring of teachers' work. The study also exposes important knowledge gaps which need urgent research attention in order to enhance NRM education in the poor rural schools of the Eastern Cape. These include analysing power and control relationships between the various agencies and agents that are involved with curriculum implementation in this education sector, and conducting investigation into the creation of specialist NRM knowledge and into the quality of NRM knowledge that is transmitted as pedagogic discourse in schools. This study contributes to the fields of rural education and environmental education in South Africa, and to the growing interest in the study of curriculum from a sociology of education perspective in the context of the country’s post-apartheid curriculum reforms.
