  • Description: M.Tech. (Chiropractic) , Purpose: This study aims to compare the effects of spinal manipulation versus mobilization of the lumbar spine and sacroiliac (SI) joints on the contractile strength of the hamstring muscle group with regards to strength and flexibility. Method: This study consisted of 2 groups of 15 participants between the ages of 18 and 50 years of age. Males and females were first separated to ensure equal male to female ratios within each group. The potential participants were examined and accepted according to the inclusion and exclusion criteria. The method of treatment administered to each group was determined by group allocation. Group 1 received spinal manipulation directed towards restrictions located within the lumbar spine and/or SI joints. Group 2 received spinal mobilization directed towards restrictions located within the lumbar spine and/or SI joints. Procedure: Treatment consisted of 4 treatment sessions with an additional follow up visit over a 2 week period. Objective data was recorded on visit 1 before and after treatment, visit 3 before and after treatment and on visit 5 in which there was no treatment administered, its purpose was purely to obtain measurements. The measurements were taken in this way in order to determine immediate as well as medium term changes. Objective data consisted of hamstring muscle strength readings taken using a handheld dynamometer and hamstring muscle flexibility readings taken using a digital inclinometer. Analysis of collected data was performed by a statistician. The manipulation and mobilization techniques used were directed towards dysfunctional joints within the lumbar spine and/or SI regions, which were detected by motion palpation. Results: Regarding muscle strength, statistically significant results were noted in Group 1 at visits 1 and 3 on both the right and left sides when determining the immediate effects of the treatment. Medium term changes were seen during the time interval between visits 1 and 3, as well as between visits 1 and 5 bilaterally. When determining the immediate effects of the treatment, Group 2 did not demonstrate muscle strength changes at visit 1 on the right, however statistically significant results were found at visit 3 on the right as well as at visits 1 and 3 on the left. Medium term changes were seen during the time interval between visits 1 and 3, as well as between visits 1 and 5 bilaterally. Manipulation and mobilization were shown to have a statistically significant effect on hamstring muscle strength, although manipulation was shown to have a more beneficial effect on muscle strength both immediately and over time, though this was only found on the left. Regarding muscle flexibility, statistically significant results were noted in Group 1 on both right and left sides at visits 1 and 3 when determining the immediate effects of the treatment. Statistically significant changes only occurred on the left between visits 1 and 5 when determining the medium term effects of the treatment. Group 2 showed statistically significant changes at visit 3 on the right as well as at visits 1 and 3 on the left when determining the immediate effects of the treatment. When determining the medium term effects of the treatment no statistically significant changes were found over the duration of the study. There was no difference found between the groups in terms of the effect that the treatment had on hamstring muscle flexibility, although isolated improvements occurred over time in the manipulation group. Conclusion: The results show that both manipulation and mobilization have a statistically significant effect on hamstring muscle strength. However, manipulation was shown to have a more significant effect. Changes in hamstring muscle flexibility were found to occur immediately and over time in the manipulation group, however only immediate effects were noted in the mobilization group. Therefore, when compared to mobilization, manipulation appears to have a greater effect on hamstring muscle strength and flexibility.

  • Description: M.B.A. , An investigation into the application of judicial case management in the South African civil court system to enhance quality and access to justice. Background The South African judicial system, and in particular, the lower Courts have been plagued by inefficiency and inadequate use of its resources. This, in turn, has lead to inordinate delays in the prosecution of both civil and criminal matters. This research will however focus on the civil prosecution of cases. Ultimately, the quality of service being provided to both internal and external customers is lacking and is evidenced by the slow pace of cases through the system. The civil justice system in South Africa is in need of an overhaul as the quality of the service provided by the courts has been questioned extensively. The focus of this research is to look at judicial case management as well as some of the current factors that may be responsible for the delays in the civil justice system and to propose judicial case management as a possible solution to enhance quality in the South African judicial system. Related to the concept of quality are productivity and efficiency and, by implication, these areas may also be improved. Accordingly, this study will assess the current situation in the South African civil justice system and investigate if judicial case management will assist in achieving quality and productivity. IV Objectives The overall objective of this study is to formulate recommendations to enhance quality and access the civil justice system. To reach the above aim, the following objectives are relavant: 1.3.1 Conduct interviews with members of the public and legal professionals involved in the civil justice system in South Africa to assess their perceptions of the system. 1.3.2 During the interviews, elicit recommendations on how the system may be improved with particular emphasis on judicial case management. 1.3.3 Conduct a literature review of relevant and available literature that investigates developments in the British, Canadian, Australian and part of the American legal system, respectively. 1.3.4 Describe and analyse the data collected. 1.3.5 Compare the data collected in the South African context with developments in international judicial systems. 1.3.6 Make recommendations with a view to improving quality in the South African civil justice system. Design and data collection A qualitative research paradigm will be used for this study. Primary data was collected using the semi-structured interview method and the in-depth interview methods, respectively, in order to determine the views among some legal professionals in the province of Gauteng as well as certain members of the public. Documentary secondary data was also used in this research project in addition to the primary data collection methods. Conclusions In summary, the conclusions can be drawn that: there are problems in the South African civil justice system that lead to increased costs, unnecessary delay and complexity of the system; the causes of the problems are related to a wide variety of issues that range from, inter alia, human resources, training, operational issues, jurisdiction of courts, the structure and functioning of the courts, pleadings and the rules of court; there is a need and a willingness for judicial case management, despite some opposition, but that nature and form thereof will have to be the subject of discussion. Recommendations Recommendations to improve the system range from improving statistical analyses; increasing the public participation process in law making; improving the sheriffs services and service of process; improving the management and administration of the courts; introducing alternative dispute resolution and possibly mandatory dispute resolution; addressing procedural issues and finally, introducing some form of judicial case management.

  • Description: New sources of enzymes for biotechnological applications are continually being sought for. While diverse microbial ecosysyems have been demonstrated in the deep subsurfaces, deep mines provide easy access to these specialist communities. Therefore, the aim of this study was to assess a deep mine biofilm as a source of novel esterase enzymes. Biofilm was collected from the Beatrix Mine in South Africa, at a depth of 808 m. Assessment of the diversity revealed a group of previously uncultured bacteria and archaea. A metagenome library was screened for esterolytic activity, producing two esterolytic clones: a phospholipase patatin protein and an isochorismatase family protein. The isochorismatase family protein contained the catalytic Asp and Cys but not the Arg, which is considered as important for catalysis. The patatin showed 55% similarity to its closest relative; the patatin family protein from Plesiocystis pacifica. The expressed patatin displayed a preference for the C6 ester and was maximally active at pH 8 and 30°C. This study reported that screening of a relatively small metagenome library from the deep mine biofilm provided two esterolytic clones, which differed from their known counterparts. This indicates that the deep mine ecosystems contain an untapped resource of novel and potentially useful enzymes which may have applications in chemical syntheses.

  • Description: M.A. , The present study examined the relationship between shyness and self-conscious emotions in terms of attribution style. Participants were administered questionnaires and then categorized into fearful shy, self-conscious shy, undifferentiated shy and non-shy groups. These four groups were then compared in terms of shyness, shame, guilt, embarrassment, and attribution style. Furthermore, the relationships between shame, guilt, and embarrassment and the different attribution styles were examined. The fearful shy, self-conscious shy and undifferentiated shy groups differed from the non-shy group in terms of the attribution styles of context and luck. The fearful shy group was found to score higher than the non-shy group in terms of context, in addition to the fearful shy as well as the self-conscious shy groups scoring higher than the non-shy groups in terms of luck. However no differences were found in terms of ability and effort between the four groups. With regards to experiencing self-conscious emotions, the fearful shy, self-conscious shy, and the undifferentiated shy groups differed from the non-shy group by scoring higher on shame. The fearful shy, self-conscious shy, and the undifferentiated shy groups also scored higher in terms of embarrassment from the non-shy group, with the fearful shy group scoring the highest followed by the self-conscious shy group and then the undifferentiated shy group. Furthermore, the fearful shy and undifferentiated shy differed from one another with the fearful shy group scoring higher in terms of embarrassment. The four groups, however, did not vary in terms of guilt. In terms of the relationship between attribution styles and self-conscious emotions, positive correlations were found between ability and shame and ability and embarrassment. A positive correlation was found between effort and guilt. Positive correlations between luck and shame and luck and embarrassment were also found. Self-conscious emotions were found to be highly correlated with shyness. Attribution styles may play a significant role in terms of an individual experiencing these emotions. Shy individuals may differ from non-shy individuals with regards to the attributions they engage in, causing them to experience self-conscious emotions to a higher extent. This may suggest a cognitive component that may be associated with self-conscious emotions. Therefore, shy individuals may be predisposed to experiencing self-conscious emotions more frequently than non-shy individuals. It is suggested that future research focus on this cognitive component in the experience of self-conscious emotions.

  • Description: Ph.D. , The purpose of this study was to explore the lived reality of the work of Human Resource practitioners in South Africa in relation to the socio-economic context of their organisations and to consider how appropriate or not their responses might be to the impacts of that context on their work. This was explored through a qualitative study wherein interviews with 50 volunteer practitioners from all types of organisations spread across the country were conducted and compared to views of 17 informed commentators in this field. It was found that the work of Human Resource practitioners is signficantly impacted by social and economic factors external to the workplace, but that the current response by practitioners is probably not as appropriate as it could or should be. A role for human practitioners as “social activists” was identified and factors influencing whether such a role is played were explored. Frameworks of appropriate actions are proposed at both strategic and individual contributor level to support this role. The role of Human Resource professional bodies in addressing social issues in South Africa is challenged and a framework proposed to improve the extent to which leadership is given to Human Resource practitioners and to increase the visibility and voice of the profession in contributing to alleviation of societal problems. Recommendations for implementation of the proposed frameworks are proposed. One of the most significant recommendations is for Continuing Professional Development to provide coaching support based on Constructive-Developmental theory to enhance the ability of Human Resource practitioners to cope with the high levels of complexity that they encounter in their roles. Further research into a proposed model of influencing factors in the social activist role is recommended.

  • Description: M. Phil. , The purpose of this study was to explore the role and experiences of the coordinators of structured mentoring schemes across various sectors of society in South Africa. A purposive sample of 25 schemes was identified and both quantitative and qualitative data was obtained through questionnaires and interviews. It was found that mentoring in South Africa, as with overseas countries, is used for a wide variety of purposes. There are varying degrees of success reported from these schemes and the predominant model of mentoring as reported in the research tends to follow the “sponsorship” approach to mentoring, which may not be the most appropriate for transformation in South Africa. Coordinators often find their roles lonely and frustrating, partly because the role is combined with other roles which take priority. Coordinators tend to initiate their own role and derive mainly altruistic role satisfaction. This initiation of the role can lead to organizational isolation and lack of management support for the mentoring scheme. Recommendations for development and support of coordinators are made.

  • Description: M.A. , Burnout due to work-related stress is an ever-increasing problem around the world. Burnout is virulent and has entrenched itself in modern corporate life making corporate workers susceptible to its effects. Mindfulness meditation training has been found to be beneficial in enhancing psychological welfare and can ameliorate the effects of burnout. Research on burnout and mindfulness has been limited within the South African corporate context. This study aimed to explore the extent of burnout among employees in a South African corporate organisation and to examine the relationship between burnout and mindfulness in the same population. It was hypothesised that burnout was prevalent and that there will be a statistically significant relationship between mindfulness and burnout. Another aim was to determine whether the OLBI and the MAAS were reliable for use in a South African context. An additional aim was to determine which variable (mindfulness, job satisfaction or social support) contributed significantly to burnout. The sample consisted of 207 participants from a bank in Johannesburg. Each participant completed a biographical data questionnaire, the Oldenburg Burnout Inventory (OLBI), the Mindful Attention Awareness Scale (MAAS), the Overall Job Satisfaction scale and the Social Support scale. The results of this research confirmed that burnout was prevalent in the organisation. However, the prevalence was not as extensive as expected. Nevertheless, results indicated that some participants were exhausted. The results provide evidence for a moderately significant negative correlation between burnout and mindfulness [r = -0.543, p <0.01]. This suggests that the therapeutic benefits of mindfulness training can potentially be accessed to ameliorate the negative effects of burnout. High reliability coefficients were found for the OLBI (alpha=0.883), MAAS (alpha=0.904), Job Satisfaction (alpha=0.732) and Social Support (alpha=0.809) scales. Three variables (mindfulness, job satisfaction and social support) explained 59.3% of the variance in burnout [F(3, 198) = 96.31, p<0.001]. Job satisfaction contributed most to burnout, recording the highest beta value [beta = -.472, p < .001]. Mindfulness was the second highest contributor [beta = -.379, p < .001], followed by social support [beta = -.175, p < .001]. Support was garnered for the use of the Job Demands-Resources (JD-R) model as a framework for examining burnout among corporate workers insofar as job resources mediated between job demands and burnout. Future studies should involve large-scale standardisation research for the OLBI and the MAAS in order to expand their use beyond their research utility and allow for their use in everyday circumstances.

  • Description: M.Ed. (Media Science) , The position of Afrikaans as a national language In South Africa has been a contested one since the 17th century settlement and occupation of the Cape by the Dutch and British settlers, and it Is not surprising that today, when the country faces critical questions relating to nationhood, cultural identity and language use In a profound way, its position again emerges as a crucial point of debate (Alexander, 1989:15). The Afrikaner group and the majority of their white South African adherents place great value on the historicity of the language. This is testified through the 'taalstryd" waged dUring an after the Anglo-Boer War (1899-1902) and the present-day status of the Afrikaans language as a major item on the negotiations agenda. This historicity and centrality of Afrikaans is contested by other language and cultural groups, who claim that Afrikaans is loaded with exclusivity and racism and that it therefore does not qualify in its claim for national status. The events of 1976 in Black schools and the subsequent years of considerable debate in public and academic forums, quite clearly Illustrates the Intensity of the contest surrounding the position of Afrikaans (Alexander, 1989:26). The Indian population group has always stressed its cultural heritage and at times this has occurred at the expense of Afrikaans as a language. Priority Is assigned to vernacular languages and Afrikaans is neglected in the process. The result is that the language is hardly spoken except in the Afrikaans classroom. It is against this background that this research project will examine the use of pictures In the teaching of Afrikaans at Indian secondary schools.

  • Description: The focus and aim of this study is twofold. Firstly it strives to ascertain whether the “green” scenarios veneered in the Bible are also ensconced within the Qur’an. Secondly, it is also imperative to determine what the mutual perceptions between Christians and Muslims are in order to enhance the possibility of dialogue in general between the two faiths. It was found that the respective and traditions of both faiths resonates with ecological similarities, amidst the theological and traditional differences. It was further found that mutual perceptions between Christians and Muslims have changed. In the vast expanse of the radical fundamentalist world of the Islam, the voices of moderate fundamentalists with liberal inclinations, however small in numbers, are heard more and more. The reciprocal element between Christians and moderate Muslims promise to secure a co-operative relationship, to inspire religious tolerance and hopefully to formulate a shared ideology. Furthermore, to orientate communities of both faiths at grassroots levels about nature conservation, a practical environmental agenda was proposed. , Prof. H. Viviers

  • Description: M.Ed. (Educational Management) , The primary purpose of this research was to investigate teachers’ experiences and perceptions of school violence directed towards them by pupils in selected South African schools. Qualitative data was collected using the interpretive approach in a case study, which was applicable because it allowed the participants to reflect on their experience in their natural setting. I used semi-structured interviews and document analysis, comprising school reports, personal journals, and newspaper articles. The sample of the study consisted of two groups of educators from each of three selected schools in Gauteng. The findings show that the participant educators experience school violence as a multifaceted phenomenon and feel that the poor management and discipline in these schools has lead to low educator morale and deterioration in the school environment, which in turn prevents effective teaching and learning. The findings also suggested that school violence takes on many forms, ranging from physical to verbal to psychological abuse. They feel they are being forced to teach in an environment polluted with threats and fear, with a resultant rippling effect of feeling unsafe and unprotected. This culminates in many educators leaving the profession either to teach abroad or leaving the government sector to work in a private teaching sector where they hope for zero tolerance of school violence. Recommendations were made for an increased level of communication between the principal and School management team (SMT) on one hand, and the educators on the other, concerning how violent attacks against educators have been addressed. Educators feel that this means of communication does not have to be labour-intensive and can be done simply by email, text message or a note during a staff or morning meeting. The presence of a counsellor or psychologist on the school premises is recommended as it will assist learners in dealing with challenges such as family factors that encompass parental separation, unstable family background, social adversities and peer pressure. The scenario that arose from this study is that a school psychologist may also be of assistance to educators, able to impart skills on anger management and offer an avenue for educators to offload their experiences of learners’ deviant behaviour. Tightening of security is also emphasised. Since the school needs good leadership, principals have to be retrained in leading the school in the new South African education dispensation. The findings revealed that this may be one of the key factors in curbing or preventing school violence. The study therefore recommends that education policymakers, school leaders and managers, parents, educators, the community and the Department of education (DoE) all work in unison to improve the school climate in those schools that are prone to school violence. Teamwork is paramount, and seminars and workshops with all stakeholders was suggested to encourage this.

  • Description: Ph.D. , Background: Most recent data have shown a slight reduction in the incidence of malaria in Nigeria. However, cases of malaria in children younger than five years of age have continued to escalate amidst ‘simple’ and ‘effective’ treatment options. The realisation of the Millennium Development Goals (MDGs) – to halve the burden of malaria by 2015 – is becoming increasingly unrealistic in Nigeria following the alarming rates of malaria in children. Apart from the ecological and environmental factors, socio-cultural and behavioural factors might be responsible for the staggering cases of malaria in children in local communities in Nigeria. It was against this background that a sociological study of health care service utilisation was conducted among caregivers of children with malaria. The study investigated the perceived threat of malaria; how the local understanding of malaria affects the recognition of signs and symptoms, perceived aetiology, treatment-seeking patterns and the use of insecticide treated nets (ITNs). The socio-generational changes in the healthcare seeking behaviour between young and older mothers as well as differences in the patterns of health care service utilisation between rural and urban subjects were also interrogated. Method: This study adopted a qualitative research design using complementary methods. A total of 40 semi-structured interviews, 20 in-depth interviews and four focus group discussions (FGDs) were conducted with caregivers and health workers. The respondents included young and older parents between the ages of 25 and 80 years whose children or wards below the age of five had manifested malaria symptoms at one time or another. A purposive sampling procedure was used to select sample for the study. The study was conducted in two selected rural areas; Okanle and Fajeromi; and one urban centre; Ilorin, Kwara State of Nigeria. Findings: The research indicated that the perceived aetiology, symptoms and treatment of malaria in children were largely influenced by the socio-cultural patterns of the communities studied. The study found that the first line of treatment for children with malaria in the communities of study was usually home treatment using traditional herbal medicines. The use of modern health care facilities is usually seen as the last resort. The traditional beliefs about causes of malaria, affordability and trust in herbal medicines, on the one hand, were found to be responsible for the widespread use of herbal medicines in the treatment of malaria in children. On the other hand, poor service delivery, lack of money, attitudes of medical personnel, mixed feelings about the efficacy of modern medicines and lack of trust in the community health centres were some factors found to be responsible for delays in seeking modern health care services when children have malaria. More importantly, the decision to seek treatment from either traditional or modern sources was largely influenced by the network of informal social interaction and social support at household and community levels. In addition, the study also found some changes in the patterns of health care seeking behaviour of young and older caregivers but generally found no differences in the patterns of health care seeking behaviour between rural and urban participants. Finally, the study found that the majority of the respondents were not aware of the effectiveness of the ITNs. Consequently, there was a high dependence on the use of traditional preventive measures which included a local leaf known as “ewe-efon” translated as “mosquito leaf”. Apart from the perceived corruption and mismanagement at the level of distribution of the ITNs, lack of appropriate knowledge about the effectiveness of the ITNs was discovered to be responsible for the widespread non-acceptance of the ITN in the prevention of malaria in children.

The study was conducted in Okanle and Fajeromi in Ifelodun Local Government Area of Kwara State. The study shows that a variation may exist between young and older caregivers with respect to desire for modern or traditional medicines in the treatment of malaria. While most senior caregivers continued to rely on herbal treatment regimens, younger parents seemed to have preference for modern treatment but not without difficulties. Given their important position within the extended family structure, senior caregivers seemed to also possess tremendous influence on health care decision making process. The study suggests the need to incorporate senior caregivers in health promotion strategy related to malaria control in rural communities.

  • Description: In this research study, the characterization of the microstructure evolution of friction stir lap welds (FSLW) of Aluminium incorporated with Titanium Carbide powder to form Aluminium based composites is presented. The Titanium Carbide powder was infused at the weld interface to produce a composite. The FSLW were conducted on an Intelligent Stir Welding for Industry and Research (I-STIR) Process Development System (PDS). Different welding parameters were used for the welding process. Rotational speeds of 1600 rpm and 2000 rpm and transverse speeds of 100 mm/min, 200 mm/min and 300 mm/min were employed. The process parameters were carefully selected to represent a low, medium and high setting for the feed rates. The microstructural evolution of the samples were studied. Optical microscope and scanning electron microscopy (SEM) techniques were used to investigate the particle distribution of the welded samples. The results obtained revealed the influence of the welding parameters on the particle distribution of the welded samples. A homogenous mixture of the materials was observed at higher rotational speed of 2000 rpm.

  • Description: D.Litt.et. Phil. (Historical Studies) , This thesis focuses on Oil and the Ijaw people of Niger Delta States: 1956 to 1998. The rationale and motivating factor is to trace the general environmental problems associated with oil production in the Ijaw village communities that have impacted on the livelihood of the Ijaw people. The thesis is the product of research conducted into the Ijaw environment before the discovery of crude oil, to determine whether their socio-economic and political activities impacted on it through conflict as a result of oil-related pollution and degradation in the 1990s. Oil was discovered in commercially viable quantities in 1956 in the Oloibiri Ijaw community. Extraction by Shell-BP and Chevron started soon afterwards. It examines the complexities of the operations, management and control strategy employed by the federal government under a joint venture agreement with the oil multinationals, particularly through the various regulatory laws passed to protect the Ijaw inhabitants and their environment. This thesis explores and investigates the impact of oil production, particularly of the perennial pollution and flaring of gas, on the soil, vegetation and climate in areas allocated to major oil producers in the Ijaw community. It contributes to existing knowledge on the responses of the federal government and the oil multinationals to pollution and its impact on the traditional fishing and farming of most Ijaws. It explains the main reason the Ijaws demanded greater control of oil resources and a fair share of revenue in the 1990s. The government’s repressive responses exacerbated the environmental struggle by the local protesters against both government and oil companies. This thesis explores the various steps undertaken by the federal government to resolve the conflict associated with environmental problems in Oloibiri, Nembe, Otuasega, Imiringi, Anyama, Kolo-Creeks, which constitute some Ijaw oil-producing communities. The performances and functioning of government agencies, such as NDDB (1961), FEPA (1988) and OMPADEC (1992), at local level are investigated. The main reason for survival strategy in adapting to the environmental problems associated with oil pollution by the Ijaws, and why they were unsuccessful, is also examined.

  • Description: M.Comm. , As part of the health care professions in South Africa, and as a profession in its own right, the importance of ethics and the management thereof for the profession of industrial psychology cannot be understated. Professional associations such as the Society for Industrial and Organisational Psychology of South Africa and the Psychological Society of South Africa may contribute to managing ethics in the profession. However, the Professional Board for Psychology (The Board) is the only regulatory stakeholder officially mandated to handle this task. Whilst the ethics management function of The Board is clearly stipulated in documents, limited research has been conducted pertaining to how The Board manages ethics in practice. An explorative study was therefore undertaken to investigate The Regulatory Stakeholders’ Perceptions of Ethics Management in the Profession of Industrial Psychology in South Africa. Such a study was deemed important since perceptions may influence how things occur in reality. By exploring the views of the members’ of The Board it was found that The Board’s ethics management functions are similar to that which has been outlined in documents. However, based on certain contradictory perceptions, additional strategies that may enhance the way in which The Board manages ethics in the profession were also identified. Ultimately this may lead to an enhancement of the way ethics is governed in the profession of industrial psychology.
