Item The Quantitative Hydrogeological Mapping of Zebediela Estates, Central Transvaal(University of the Witwatersrand, Johannesburg, 1970-05) Pretorius, Desmond AubreyThe groundwater system on zebediela Estates, situated along the northern edge of the Springbok Flats in the Central Transvaal, has been studied by physiographic, geologic , geophysical, geochemical, and hydrologic methods . Emphasis has been placed on the subsurface mapping of the spatial distribution patterns of a nvn1ber of hydrogeologic parameters, and computer-based polynomial trend surface analysis has been employed to facilitate the interpretation of the maps. The computer has also been used to determine the general statistics of the frequency distributions of the various parameters and to platform sequential multiple linear regression analysis in an attempt to determine the relationships between the variables . Data arrays of observations, computations, and interpretations have been disp layed in 38 tables in the text and 21 appendices to the text . The distr ibution patterns , in one and two dimensions, have been portrayed in 8 text figures and 117 maps, separate from the t ext. The area studied covers approximate ly 23 square mil es, in which 556, 000 orange trees have been planted on 5800 acres . An average annual amount of 2400 million gallons of water is required to maintain t he operation, and 560 million gallons of this quantity are withdrawn, on the average, each year from boreholes tapping the groundwater resources of the Estates . Up to April, 1969, 315 holes had been drilled, and 151 had become producers at one time or another. In 19 years of exploitation between 1950 and 1968, 10, 600 million gallons of groundwater were withdrawn, at an average rate of 13 million gallons per year per production borehole. The study has shown that the groundwater system supplying this substantial quantity of water consists of two main elements - a piedmont alluvial slope, in which stream channels and paleochannels on coalescing alluvial fans are acting as conduits for the transmistion of water from the intake areas; and an underlying bedrock storage reservoir composed of aquifers of the Transvaal and Karroo sequences . The Malmani dolomite aquifers and the Stormberg basalt aquifers are superior to those of the Wolkberg quartzites, shales, and lavas, and the Stormberg Cave sandstones. It has been possible to distinguish two cycles of Karoo basalts, each of which shows differentiation . The upper cycle is far more important as an aquifer than the lower cycle. The piedmont slope is composed of portions of three alluvial fans , the spines of which have a general southeasterly trend towards the junction of the Nkumpi and Olifant rivers in the valley-flat environment well to the south of the Estates . The upland areas above the apices of the fans embrace the mountain ranges which form the northern rim of the Transvaal Basin, and these uplands have suffered right-lateral movements along extensive east-northeast-trending transcurrent faults which must have continued to be active into recent times in order to displace the stream course on the fans. The fan-head section and portion of the midfan section of the Nkumpi fan, in which the Gompies River is situated, occur over the east-central, eastern, and southeastern parts of the property, and, where underlain by the upper basalt aquifers, constitute the most important source of groundwater on Zebediela Estates. The whole of the fan-head and mid-fan sections of the Mamukebe fan are located in the riorthern, west-central, western, and southwestern localities of the area studied. The fan is much smaller than either of the others, and is underlain by Wolkberg rocks, Cave sandstones, and lower basalts. Its overall groundwater potential is consequently lower than that of either of the other two components of the piedmont slope. Only a very restricted portion of the fan-head section of the Mogoto fan occurs in the extreme northwestern corner of the Estates, where it is underlain by the dolomite aquifer, Its groundwater parameters are consequently very favourable, but the true potential of this fan lies beyond the western boundary of the property. The average yield of boreholes in the upper basalt is 3600 gallons per hour; in the lower basalt, 2000 g.p.h.; in the sandstone, 1500 g.p.h.; in the dolomite, 11,200 g.p.h.; and in the quartzites, 1500 g.p.h. The average yield for all boreholes on the Estates is 4100 gallons per hour. All of these figures are appreciably higher than those for equivalent formations elsewhere in South Africa, testifying to the impoi,tance of the piedmont alluvial slope environment in the overall groundwater system at Zebediela. The average annual recharge of the groundwater reservoirs from all sources has been estimated at 700 million gallons. With the average annual withdrawal being of the order of 560 million gallons, the possibility exists that production from the aquifers can be increased by 25 per cent, without fear of serious, permanent deterioration in the performance of the groundwater system. However, excessive exploitation in times of low recharge might lead to the development of quality h.azards with respect to sodiuum, ehloride, and bicarbonate over the upperbasalts. This possibility does not exist for the remaining aquifers, particularly those in the dolomite, from which relatively pure water is drawn. An added problem in the recharge of the upper basalt aquifer is the contamination of t he groundwater in storage by lithium, brought into the Zebediela groundwater- system by the Nkumpi River, which transmits the element from the granite terrain to the north of the mountainous rim of the Springbok Flats. A new model of groundwater exploration has been devised, based on optimum drilling sites being located where coincidence takes place of piedmont stream channel conduits, dolomite or upper basalt aquifers, and transcurrent fault aquicludes, Results obtained from the employment of this model during two years of drilling subsequent to its development in a preliminary form produced an increase of 14 per cent in the average yield of all boreholes drilled.Item Man-The-Shaman is it the Whole Story? A Feminist Perspective on the San Rock Art of Southern Africa(University of the Witwatersrand, Johannesburg, 1995-06) Stevenson, Judith S.Ethnographic accounts show that both shamanic and gender rituals play a critical role in San culture. Although 30% of the women and 50% of the men become shamans, the literature investigating San rock art frequently defines 'Man-the-Shaman' and minimizes the feasibility of female depictions of this important social role. Prior rock art research has tended to separate shamanic and gender processes to the impoverishment of both. This dissertation investigates the symbolic connections between these two social spheres, and argues that they are inseparable. Through this examination of gender and shamanic roles in San society this dissertation argues that metaphors reflect these two social spheres. It also argues that metaphors are a way of life which are expressed both in reality and non-reality. With these points in mind, it investigates the role of men and women as related to San rock art through social roles.Item Record review of patients with brain abscess and empyema.(University of the Witwatersrand, Johannesburg, 2010-01-22T10:28:25Z) Schwenke, Katherine LindaStudies of patients presenting with brain abscess (BA) and Empyema are not routinely focused on occupational therapy (OT). There is a paucity of literature on deficits other than hemiplegia. Aims of this study were to determine the relationship between BA, Empyema, motor and other deficits and whether an OT intervention protocol is needed. Record review was used to establish clinical presentation trends. Hemiplegia was the most common motor deficit and the majority scored below the norm on the Beery- Buktenika Developmental Test of Visual Motor Integration (VMI). Patients with Brain Abscess generally had more significant deficits than those with Empyema for both motor and process deficits. Part B followed up a small sample (n=8) which indicated clinical improvement on the VMI test with the score on the supplemental test of motor coordination remaining a concern. Occupational Therapy is recommended to address these issues based on the Occupational Therapy Practice Framework-II.Item The effect of a scissor skills program on bilateral fine motor skills in preschool children in South Africa including skill improvement, equivalence, transferability of skills and skill retention(University of the Witwatersrand, Johannesburg, 2010-01-27T12:43:24Z) Ratcliffe, IngridThe purpose of this study was to assess the improvement of scissor skills after a graded scissor skills program in preschool children in South Africa (SA). A bilateral fine motor skills assessment tool was developed for use in this research. This task-based assessment included every day activities required at school as well as personal management items. This research phase included the development of the test items and test instructions, scoring as well as validity and reliability testing of the assessment. A suitable scissor skills program was then developed for Grade 0 children in South Africa. The program was validated by a pilot study and also by a focus group of occupational therapists. Some changes were made to the picture selection, the grading of the program, as well as to teacher instructions on how to present the program before it was finalised and ready for use in the implementation phase of the research study. The implementation phase of the study included the individual assessment of 149 learners (mean age of 5 years 6 months), from three different schools in South Africa. The main aim was to establish the effectiveness of the scissor skills program by measuring skill improvement, transferability of skills and skill retention. A further aim was to compare the difference of skill levels of learners from various socio-economic backgrounds in South Africa. The results showed statistically significant improvement in scissor skills in all groups from the three different schools, as well as an ability to retain the learnt skills. Participants from lower socio-economic backgrounds demonstrated the least skill initially but made the greatest gains during the program, at times decreasing the gap between themselves and other participants. It was concluded that children benefited from a graded scissor skills program, which allowed them to improve and retain their scissor skills but improvement did not transfer to other fine motor tasks.Item The role of regulatory T cells in adults in South Africa with active tuberculosis(2010-01-28T10:11:24Z) Mayne, Elizabeth SarahIntroduction: Regulatory T cells (Tregs) are increasingly being recognized as key immunological players in immunosuppression and have been seen to be permissive for certain infections. Aim: This study aimed to elucidate the role that Tregs play in symptomatic infection with Mycobacterium tuberculosis (TB), both with and without co-infection with human immunodeficiency virus type 1 (HIV 1) by quantification of these cells at ex vivo. It was then attempted to characterise the behaviour of FoxP3 positive cells in culture with stimulation. Methods: Peripheral blood mononuclear cells were purified from uninfected controls, patients with active TB, patients with HIV infection and patients with HIV infection and active TB. The frequencies of Tregs were assessed by flow cytometry at ex vivo and again after four days of culture with stimulation with anti-CD3, Purified protein derivative, tetanus toxoid and HIV peptide superpools (gag and nef). These frequencies were compared between the four groups of patients. The ability of Tregs and effector T cells to proliferate was also assessed. Interferon-γ secretion was used as a measure of effector T cell response to stimulation. vi Results: Frequencies of Tregs were significantly reduced in patients with active TB as compared with HIV infected patients and uninfected controls. Co-infected individuals showed a broad range of frequencies which were not significantly different from controls. These frequencies remained stable in culture with the exception of those individuals infected with HIV who showed a decline in the frequency of those cells expressing FoxP3 over the period. Cells expressing FoxP3 were not anergic and responded to stimulation. HIV specific proteins, in addition, resulted in specific effects on the Tregs with a positive interferon response to gag correlating with increased Treg frequencies and FoxP3 expression in CD4+ T cells correlated with the proliferative response of CD4+ T cells to Nef in HIV infected individuals. Conclusions: This study shows significant differences of frequencies of FoxP3 positive producing cells in the peripheral blood at ex vivo in patients with active TB. The function of these cells in this population is uncertain and further functional data and long-term clinical follow-up is required. In addition, the frequencies of these cells remained constant over time and showed proliferative response to stimuli (most notably CD3) suggesting that these cells may be generated in the periphery.Item The impact of lower limb amputation on quality of life: a study done in the Johannesburg Metropolitan area, South Africa(University of the Witwatersrand, Johannesburg, 2010-01-29T07:15:06Z) Godlwana, Lonwabo L.Background: The impact of non-traumatic lower limb amputation on participant’s quality of life (QOL) is unknown. In an effort to provide better care for people with lower limb amputation, there is a need to first know the impact of this body changing operation on people’s quality of life. Aim of the study: To determine the impact of lower limb amputation on QOL in people in the Johannesburg metropolitan area during their reintegration to their society/community of origin. Objectives: 1. To establish the pre-operative and post-operative: QOL of participants (including the feelings, experiences and impact of lower limb amputation during the time when they have returned home and to the community). The functional status of participants. Household economic and social status of these participants. 2. To establish factors influencing QOL. Methods: A longitudinal pre (amputation) test –post (amputation) test study utilized a combination of interviews to collect quantitative data and in-depth semi-structured interviews to gather qualitative data. Consecutive sampling was used to draw participants (n=73) for the interviews at the study sites pre-operatively. The three study sites were Chris Hani Baragwanath Hospital, Charlotte Maxeke Johannesburg General Hospital and Helen Joseph Hospital. Participants were then followed up three months later for post-operative interviews and key informants were selected for in-depth interviews (n=12). Inclusion criteria: Participants were included if they were scheduled for first time unilateral (or bilateral amputation done at the same time) lower limb amputation. The participants were between the ages of 36-71 years. Exclusion criteria: Participants who had an amputation as a result of traumatic or congenital birth defects were excluded from the study. Participants with comorbidities that interfered with function pre-operatively were not included. Procedures: Ethics: Ethical clearance was obtained from the Committee for Research on Human Subjects at the University of the Witwatersrand and permission was obtained from the above hospitals. Participants gave consent before taking part in the study. Instrumentation: A demographic questionnaire, the EQ-5D, the Modified Household Economic and Social Status Index (HESSI), the Barthel Index (BI) and semi-structured in-depth interviews were used. Data collection: Participants were approached before the operation for their preoperative interviews using the above questionnaires and then followed up postoperatively using the same questionnaires and some were selected to participate in semi-structured in-depth interviews three months later. Pilot study: The demographics questionnaire and the modified HESSI were piloted to ensure validity and reliability. iii Data analysis: Data were analyzed using the SPSS Version 17.0 and STATA 10.0. The significance of the study was set at p=0.05. All continuous data are presented as means, medians, standard deviations and confidence intervals (CI 95%). Categorical data are presented as frequencies. Pre and post operative differences were analyzed using Wilcoxon Signed-rank test. A median regression analysis (both the univariate and multivariate regression) was done to establish factors influencing QOL. Pre and post operative differences in the EQ-5D items and the BI items were analyzed using Chi square/Fischer’s exact depending on the data. Data were pooled for presentation as statistical figures in tables. Both an intension to treat analysis and per protocol analysis were used. A grounded theory approach was used to analyze the concepts, categories and themes that emerged in the qualitative data. Results: Twenty-four participants (33%) had died by the time of follow up. At three months, n=9 (12%) had been lost to follow up and 40(55%) was successfully followed up. The preoperative median VAS was 60 (n=40). The postoperative median VAS was 70. The EQ-5D items on mobility and usual activities were reported as having deteriorated significantly postoperatively (p=0.04, p=0.001respectively) while pain/discomfort had improved (p=0.003). There was no improvement in QOL median VAS from the preoperative status to three months postoperatively The preoperative median total BI score was (n=40). The postoperative median total BI score was 19. There was a reduction in function (median BI) from the preoperative status to three months postoperatively (p<0.001). The ability to transfer was improved three months postoperatively (p=0.04). Participants were also found to have a decreased ability to negotiate stairs (p<0.001). Mobility was significantly reduced three months postoperatively (p=0.04). During the postoperative stage (n=40), 38% of the participants were married. Most (53%) of the participants had no form of income. The highest percentage of participants in all instances (35%) had secondary education (grade10-11), while 25% had less than grade 5. Only one participant was homeless, 18% lived in shacks, 55% lived in homes that were not shared with other families. People with LLA in the Johannesburg metropolitan area who had no problem with mobility preoperatively (EQ-5D mobility item), who were independent with mobility (BI mobility item) preoperatively, who were independent with transfer preoperatively (BI transfer item) had a higher postoperative quality of life (postoperative median EQ-5D- VAS) compared to people who were dependent or had problems with these functions preoperatively. Being females was a predictor of higher reported quality of life compared to being male. Emerging themes from the qualitative data were psychological, social and religious themes. Suicidal thoughts, dependence, poor acceptance, public perception about body image, phantom limb related falls and hoping to get a prosthesis were reported. Some reported poor social involvement due to mobility problems, employment concerns, while families and friends were found to be supportive. Participants had faith in God. Conclusion: Participants’ QOL and function were generally scored high both preoperatively and postoperatively but there was a significant improvement in QOL and a significant reduction in function after three months although participants were generally still functionally independent. Good mobility preoperatively is a predictor of good QOL postoperatively compared to people with a poor preoperative mobility status. Generally, most participants had come to terms with the amputation and were managing well while some expressed that they were struggling with reintegration to their community of origin three months postoperatively with both functional and psychosocial challenges.Item The Development of Social Capital in the Judiciary through mentorship(2011-04-06) Engelbrecht, Naomi AnnetteThis study analyses the concept of mentoring as used in the South African Judiciary. Mentoring has been adopted by the South African judiciary in order to enhance the potential of acting Regional Magistrates to address their often repeated grievances regarding capacity building. The research attempts a quick evaluation of the process so far.Item Caught in a gap? An examination and human rights assessment of immigration detention laws and practices in South Africa(2013-03-19) Tay, RoannaAbstract: This study examines the laws and practices relating to immigration detention in South Africa. It provides an in-depth examination of the legislation, with reference to known state practices and cases where migrants have been subjected to prolonged and repeated periods of immigration detention. The study highlights gaps in South African law that contribute to certain categories of migrants being especially vulnerable to immigration detention. Four categories are identified: (1) asylum seekers; (2) persons with difficulty obtaining travel documents; (3) stateless person; and (4) persons subject to other prohibitions against refoulement. The study offers recommendations for legislative reforms to fill the gaps in the law that contribute to these migrants’ vulnerability to immigration detentionItem Human Resources Development at Tumela Mine(University of the Witwatersrand, Johannesburg, 2014-01-21) Mphahlele, MatukuIn the context of the South African mining and mineral sector this study explores the human resource development measures to transform mentoring programmes at Tumela Mine. Despite the legislative stipulations that seek to promote equitable access to participation in the creation, development and sharing of the South African economy and natural resources through the establishment of a workplace environment conducive for learning to take place, little is known on how Tumela Mine implements mentoring programmes to foster effective human resource development. The study explored and analysed participants’ perceptions regarding the implementation of the Tumela Mine Mentoring Programme. The research was conducted through the use of a case study approach, and primary data was collected from respondents, and secondary data was gathered from relevant policies, minutes of meetings and company annual reports. The research questioned the successful aspects in the Human Resource Development unit, challenges and management’s responses to impediments to the implementation of mentoring programmes at Tumela Mine. The findings indicate that two key issues to improve implementation of mentoring programmes at the Tumela Mine are a transformational style of management and strategic repositioning of the mentoring programmes. The research argues that although company corporate strategic policy formulation and planning seek to promote equal participation of all employees in mentoring relationships, programme interventions at an operational level make it difficult to promote mentoring programmes. The key recommendation is that in order to implement effective mentoring programmes the company should review the corporate business strategy focused on strategic repositioning of mentoring programmes and inspire visionary leadership to implement a transformational style of management.Item Human Resources Development at Tumela Mine(University of the Witwatersrand, Johannesburg, 2014-01-21) Mphahlele, MatukuIn the context of the South African mining and mineral sector this study explores the human resource development measures to transform mentoring programmes at Tumela Mine.

A qualitative case study based on document analysis of 70 documents, 39 interviews and 2 focus groups was the vehicle for examining the role of the leadership at the Islamic University of Gaza (IUG). IUG has operated under complex conditions of occupation and ongoing turbulence from its inception in 1978 to the present. This study examines the period 1978-2012. In this time the university grew from 25 men studying Sharia in a tent to 20,000 students (63.7% female) studying across 11 faculties and 112 different specialisations. The study documents and labels four phases of development of the university. The patterns of leadership uncovered in the study include transformational, transactional, heroic, post-heroic and on some specific occasions authoritarian styles, with transformational being the most important. The way in which the leadership resolved short term crises, as well as their long-term and big-picture focus, shaped the development of the university. Resilience theory was applied alongside leadership theory to analyse the responses of IUG leadership. Resilience was taken beyond surviving to capitalising on disruption. Twenty three markers of resilience were found which worked independently and interactively to support resilient responses to the challenges IUG faced. These factors were initially developed from the literature, and new factors were added based on this research. The relationship between leadership styles and the promotion of resilience was examined. The thesis describes a mutual shaping and supporting role between university and society in Gaza, and discusses some of the paradoxes of help and harm coming from players and belief systems external to the university. The paradox of faith which can provide a cohesive, binding set of beliefs to support staff and students, as well as being the source of conflict and harm, is also discussed. A definition of a university as an educational community functioning beyond place, buildings, external recognition, or physical destruction was developed.Item The principles governing 'place of effective management' and 'permanent establishments' and their application to the digit al economy: a South African perspective(2016) Boel, KatherineThe purpose of this research report is to consider the application of existing 'place of effective management' (POEM) and 'permanent establishment' (PE) principles to a company operating in a digital economy in order to determine its appropriateness and limitations. This paper is broadly divided into four parts. The first part of the paper provides a brief background to the above taidng principles and the digital economy. The second part considers, in detail, the guidance and factors that are currently available on how the POEM and the creation of a PE for a company may be determined both internationally and from a South African tax perspective, including the role of the residency tie-breaker article and the PE article in most double taxation agreements (DTA's) with South Africa. The third part of the paper considers how these guidelines and factors may apply to the digital economy and the practical challenges which arise. Finally, the paper seeks to identify possible alternatives to overcome the pitfalls in the POEM and PE interpretations and to highlight aspects which require further consideration.Item Customer and employee-based brand equity driving United Bank for Africa's market performance(2017) Uford, Imoh CharlesWith increased competition in the banking industry, particularly in developing economies, United Bank of Africa Plc (UBA) in Nigeria has been thriving. The bank is a multinational financial services provider, which operates in 22 African countries. It also has offices in the US, UK and France. UBA has about 626 global branches and serves more than seven million retail, commercial and corporate global customers. Positioned as a pan-African bank, the UBA Group is firmly in the forefront of driving the renaissance of the African economy. It is also well positioned as a one-stop financial services institution, with growing reputation as the face of banking on the African continent. UBA Plc has grown over the years from being just a brand name to a house hold name in Nigeria. In 2011, it was reported that UBA’s total assets was worth about $12.3 billion. The bank is also gearing to be one of the dominant and leading banking brands in Africa. While the measurement of UBA’s asset worth is important as it reveals information of its financial performance, it can be more important to measure the worth of its intangible assets, which is being captured from the assessment of its brand equity. Brand equity does not only comprise of an organization’s intangible assets, but does reflect the values consumers hold of a brand and can also secure long-term commercial and competitive advantages for companies. With the notion that the value or power of a brand lies in what customers perceive in their minds concerning the brand, most studies have measured brand equity mainly from the customer-based brand equity (CBBE) perspective using Aaker’s (1996a) and Keller’s (1998) models. Aaker’s (1996a) model is however considered to be the most comprehensive CBBE model and it measures brand equity from five dimensions – brand awareness, brand association, perceived quality, brand loyalty and proprietary assets. While CBBE can secure long-term market performance, it is being recommended that the contribution of employee-based brand equity (EBBE) should also be measured. This is particularly important in the service sector, such as banking, where “what is delivered is less important than how it is delivered”. More so, with the increasing importance of internal branding, there is a need to measure EBBE, which assesses how knowledgeable, happy and committed employees are willing to deliver on the brand promises to build brand equity. In addition to the importance of measuring both CBBE and EBBE, there is also the need to further compare the extent to which both CBBE and EBBE predict market performance, an outcome anticipated, but rarely empirically tested. This study therefore employs Aaker’s (1996) CBBE model and Kwon’s (2013) EBBE model to examine the sources of UBA’s CBBE and EBBE respectively and the extent to which each of the equities drive market performance indicators, such as consumer purchase intention, willingness to pay a price premium and brand preference. A positivist research paradigm with a quantitative survey of 182 UBA employees and 178 UBA customers were used to test the hypotheses. The relationships hypothesized in the conceptual model were empirically tested using structural equation modeling (SEM). The results indicated that the conceptual model satisfactorily fitted the data and provided reasonable explanations among variables. In terms of the relationships, it was found that UBA’s CBBE was accounted for by brand associations or image and brand loyalty. UBA’s overall CBBE positively and significantly affected all the market performance indicators of purchase intention, willingness to pay a price premium and brand preference. UBA’s EBBE which was found to be positively and significantly driven by role clarity and brand commitment could only positively and significantly predict the bank customers’ willingness to pay a price premium. Conclusively, it was found that while UBA’s EBBE make some contribution to the bank’s market performance, its CBBE is the major driver of its performance. This study theoretically contributes by not only empirically testing Aaker’s (1996b) CBBE and Kwon’s (2013) EBBE in the Nigeria’s banking sector, but by also showing how both models explain market performance. Practically, the study reveals sources of CBBE and EBBE, which not only UBA should prioritize in improving their market performance, but other service sectors in Nigeria and the continent should take special note of. Keywords: Brand equity, customer-based brand equity (CBBE), employee-based brand equity (EBBE), United Bank for Africa (UBA) Plc, United Bank for Africa (UBA) Plc, structural equation modelling (SEM), United Bank for Africa (UBA) Plc, willingness to pay a price premium and brand preferenceItem Tax deductibility of interest and finance charges: the real cost of credit(2017) Haines, ChantelleBorrowers will commonly incur various finance charges when acquiring loan funding, which may include, inter alia, interest expenditure, guarantee fees, introduction fees, commitment fees and service fees. The tax deductibility of these finance charges is an important consideration for borrowers. Prior to the amendment of the definition of ‘interest’ in section 24J of the Income Tax Act 58 of 1962 (as amended), related finance charges were deductible for tax purposes. The term related finance charges was interpreted very widely by the Supreme Court of Appeal in C:SARS v South African Custodial Services (Pty) Ltd1 to include guarantee fees, introduction fees, commitment fees and even selected service fees. It is submitted that following the recent amendment of the interest definition by the Taxation Laws Amendment Act 15 of 2016, to now allow the deduction of ‘similar finance charges’ rather than ‘related finance charges’ the tax treatment of finance charges are uncertain. The objective of this study is to evaluate how this amendment will affect the deductibility of finance charges incurred by borrowers for tax purposes. The study proposes to first evaluate whether finance charges will be deductible in terms of section 24J, consider the definition of ‘interest’ and provide some general tests aimed at assessing the ‘trade requirement’ and the meaning of the phrase ‘in production of income’. The impact of the anti-avoidance legislation in sections 8F and 8FA will be considered, and finally, a brief discussion of the deductibility of finance charges in terms of the general deduction formula in section 11(a) read with section 23(g).Item Implementation of the mental health care act in psychiatric hospitals(2017) Mulutsi, Eva NkengIntroduction Mental illness is prevalent in all regions of the world and contributes significantly to premature mortality, high morbidity and loss of economic productivity (Baxter, Whiteford, Vos, & Norman, 2011; Charlson, Baxter, Cheng, Shidaye, & Whiteford, 2016). In South Africa, the Mental Health Care Act (No 17 of 2002) was promulgated in 2004 in response to the high burden of mental illness and to improve mental health service delivery, within a human rights framework. Aims and Objectives: The overall aim of this PhD study was to examine the implementation of the Mental Health Care Act in psychiatric hospitals in South Africa. The specific objectives were to: explore stakeholders’ involvement in the implementation of the Act; examine the policy processes followed in the implementation of the Act; determine whether Mental Health Review Boards execute their prescribed roles and functions; examine the implementation of legal procedures for involuntary admissions of psychiatric patients; and identify factors that influenced the implementation of the Act. Methods: The study was approved by the Human Research Ethics Committee of the University of Witwatersrand, Johannesburg. Sixteen psychiatric hospitals were selected in nine provinces, through stratified random sampling. Using an adapted conceptual framework with policy implementation theory as its foundation, the overall study approach was qualitative in nature, complemented with a record review of involuntary patient admissions in the selected hospitals. The qualitative component consisted of 35 in-depth interviews with: the drafter of the Act (n=1); provincial mental health coordinators (n=9); a psychiatrist at each of the selected hospitals (n=16); and the chair of a Mental Health Review Board in each of the provinces (n=9). At each selected psychiatric hospital, five patient records were selected randomly (n=80), focusing on compliance with the legal procedures for involuntary admissions. The qualitative data were analysed using thematic content analysis and MAXQDA® 11 while STATA® 12 was used to analyse the data from the record reviews. Results: South Africa’s political transition created a window of opportunity for the implementation of the Act. Wide-spread stakeholder support for the spirit and intention of the Act, advocacy for human rights, the broader transformation of the health system, and the need for enhanced governance and accountability in mental health, facilitated the implementation of the Act. However, implementation was hindered by: the relatively low prioritisation of mental health; stigma and discrimination; poor planning and preparation for implementation; resource constraints; and suboptimal stakeholder consultation. The study found that the majority of involuntary psychiatric patients admitted during (the year) 2010 were single (93.8%), male (62.5%), and unemployed (85%), predominantly black African (80%), with a median age of 32.5 years. The primary diagnoses were schizophrenia (33/80), substance-induced psychosis (16/80), bipolar mood disorders (15/80) and acute psychosis (9/80). There was poor compliance with the prescribed procedures for involuntary psychiatric admissions, exacerbated by suboptimal governance by, and functioning of, the Mental Health Review Boards, thus resulting in de facto illegal detention of patients. Conclusion and Recommendations: The Mental Health Care Act is an important policy lever to address the burden of mental illness and ensure quality mental health service delivery in South Africa. However, the enabling potential of the Act can only be realised if the following issues are addressed: improved, and dedicated resources for mental health; training and capacity building of health professionals and hospital managers on key aspects of the Act; improved governance, leadership and accountability through well-functioning Mental Health Review Boards; and improving mental health infrastructure and community-based services.Item Assessing alternative monetary policy frameworks and instruments in selected African economies(2017) Chiumia, Austin BelewaThis thesis contains three core chapters that assess the performance of alternative monetary policy frameworks and instruments in stabilizing 10 selected African economies. Literature and practice show that Advanced Economies (AEs) and Emerging Market Economies (EMEs) are mostly adopting the ination targeting (IT) framework. This framework relies on active use of the interest rate as a policy instrument for macroeconomic stabilisation. Di⁄erent from AEs and EMEs, the majority of African countries are characterized by low nancial market development, frequent supply shocks and volatile terms of trade. These features impede the e¢ ciency of the IT framework and the interest rate instrument. Supply shocks imply that ination is not only demand driven. Volatile terms of trade translate into excessive exchange rate uctuations. Due to these factors, policy practice in Africa remains largely divergent from the global trend. Authorities still rely on monetary aggregate targeting (MAT) with de facto managed exchange rates. However, the MAT framework is also failing to stabilize economies. This follows instability of the key factors, such as the money demand, upon which the framework is anchored. Furthermore, controlling exchange rate movements is a challenge due to weak balance of payments positions. It is not surprising, therefore, that the majority of African economies still remain in the grip of macroeconomic instability. Ination and GDP targets are rarely met and they also remain volatile. The perverse macroeconomic features and the perceived failure of the MAT regime have necessitated the search for alternative monetary frameworks and instruments. In this study, we join the search by specically focussing on three questions. First, given the macroeconomic landscape in Africa, what is the relative performance of the interest rate vis--vis the monetary aggregate as instru ments for macroeconomic stabilization? Secondly, how do these instruments perform when apart from ination and output stabilization, monetary policy also engages in smoothing exchange rate uctuations? Thirdly, what is the relative performance of ination targeting vis--vis nominal GDP targeting as alternative monetary policy regimes for macroeconomic stabilization in African economies? Although the success of monetary policy largely relies on appropriate conguration of monetary policy frameworks and instruments, answers to these questions remain controversial and scanty for African economies. In order to address these questions, we formulate a New Keynesian Dynamic Stochastic General Equilibrium (DSGE) model. In this model, money is non-separable from consumption in the utility function. We estimate the model using the Maximum Likelihood method with quarterly data mostly from 1990 to 2014. The data is obtained from the International Financial Statistics (IFS). The thesis has ve chapters. Chapter 1 is the general background to the research problem. Chapters 2, 3 and 4 are distinct but related core chapters addressing three specic research questions. Chapter 5 is the conclusion. In Chapter 2, we compare the performance of the monetary aggregate and the interest rate as alternative instruments for stabilizing ination and output in 10 selected countries. Results show that the monetary aggregate is superior in stabilizing 5 economies. In the other 5 countries, it is the interest rate instrument which performs better. In the former group of countries, the monetary aggregate plays a relatively large role in macroeconomic dynamics while in the latter the interest rate is more signicant. These results partly reect di⁄erences in nancial market development between the two groups of countries. Overall, we nd a weak role of the interest rate compared to the monetary aggregate in driving aggregate demand dynamics. The exchange rate is also found to be a key driver of macroeconomic dynamics. Our re v sults suggest three things: First, authorities in Africa need to be cautious of a blanket adoption of the interest rate as a sole monetary policy instrument. Second, authorities will nd it di¢ cult to stabilize economies using the interest rate based frameworks. Third, exchange rate stability is key to macroeconomic stability in Africa. In Chapter 3, we extend the authoritiesobjective function. In addition to minimizing ination and output volatility, authorities also use the interest rate or money supply rules to smooth exchange rate uctuations. The results show that macroeconomic performance is enhanced when authorities smooth exchange rate uctuations in 4 of the 10 countries. The gains from exchange rate smoothing mostly arise from a reduction in ination and exchange rate volatility but not fromoutput. In the other 6 countries, exchange rate smoothing worsens macroeconomic performance. These results reect the fact that the exchange rate exerts a relatively large inuence in macroeconomic dynamics in the rst group of countries compared to the latter. Exchange rate smoothing therefore minimizes the pass-through of the exchange uctuations to ination and output leading to better performance. Overall, the ndings suggest that exchange rate smoothing is harmful in Africa. Where exchange rate smoothing delivers gains, appropriate thresholdsofsmoothingneedtobeobservedtoavoidpolicyinducedmacroeconomic instability. Authorities should also smooth temporal rather that structural shifts in the exchange rate level. In Chapter 4, we compare the performance of ination targeting (IT) vis-vis nominal GDP targeting (NGDPT) as alternative monetary policy frameworks for macroeconomic stabilization. We examine the strict and exible versions of these policy regimes. We also include a hybrid regime which combines elements of IT and NGDPT. Results show that the hybrid regime performs better in 5 countries. In the other 4 countries, it is the strict ination targeting that performs better. In 1 country, exible ination tar vi geting is optimal. The results also reveal that demand shocks dominate but are closely trailed by supply and exchange rate shocks in explaining macroeconomic uctuations. The multiplicity of signicant shocks is key in explaining the dominance of the hybrid regime. The hybrid regime successfully handles shocks that can neither be optimally handled by the IT regime nor the NGDPT regime alone. These results have several implications. First, demand management alone is insu¢ cient to stabilize African economies. Second, identifying dominant shocks is critical for choosing robust monetary policy regimes. Third, the multiplicity of signicant shocks implies that choosing monetary policy frameworks and hence macroeconomic management process is more complex for African policy makers. Overall, the results have several policy implications which are outlined in Chapter 5. First, they suggest a cautious approach towards generalized adoption of the interest rate over the monetary aggregate as a monetary policy instrument in African economies. This contradicts the current wave of monetary policy changes sweeping across African countries. Secondly, the signicanceoftheexchangeraterenderscredencetoexchangeratesmoothing in Africa. The ndings, however, suggest that exchange rate smoothing can either enhance or worsen macroeconomic performance. Where it enhances macroeconomic performance, authorities must carefully consider the thresholds of smoothing to avoid creating macroeconomic instability. Authorities need not ght structural shifts in exchange rates levels through smoothing. This would help to preserve the shock absorbing role of the exchange rate. Finally, the prevalence of demand, supply as well as exchange rate shocks makes the hybrid monetary policy regime which combines elements of IT regime as well as NGDPT regime to perform relatively better in stabilizing the majority of the economies. Given the multiplicity of shocks, authorities inAfricaneedtocomplementdemandmanagementwithpoliciesthataddress supply side and exchange rate bottlenecks to ensure sustainable macroeco vii nomic stability. Overall, the ndings suggest that there is scope to improve monetary policy performance in Africa by adopting suitable frameworks and instruments. The results also highlight the problem of tackling monetary policy issues with a "one size ts all" approach.Item An Experimental test of the endowment effect(2017) Cohen, Justin SimonIn this study, I use a computer game based lab experiment to investigate the existence of the Endowment Effect. Previous empirical evidence has been criticised for failing to adequately account for the effects of transactions costs and other frictions. The structure of the game used in this study allows me to control for these effects, and the results provide evidence in support of the existence of an Endowment Effect. The effect is found to be stronger when transactions costs are present.Item Impact of oil price shocks on stock returns: evidence from selected Southeast Asian economies(2017) Siddiqui, Ammar AhmedThis paper investigates the impact of oil price shocks on stock market returns in selected Southeast Asian countries. We selected five countries, those are Indonesia, Singapore, Malaysia Thailand and Philippine. We employ autoregressive distributed lag model (ARDL) and VECM model in the analysis. We model both positive oil price shock and negative oil price shock. We find that the real Brent price is positively correlated with all the stock markets in the selected countries. The results of ARDL model indicate that positive oil price shock exhibits a negative impact on the stock market returns while lag one negative oil price shock exhibits a positive impact on the stock market returns in the short run. However, only Indonesia and Singapore exhibit a significant response to positive and negative oil shocks in the ARDL model. The cointegration analysis indicates a long run causal relationship from oil price to stock market returns for Malaysia and Singapore. This result is confirmed by the error correction model with significant and negative but low speed of adjustment.Item The arm’s length pricing for intra-group services – transfer pricing(2017) Lee, Yi YingThe purpose of this research report is to identify any improvements that can be made to the South African transfer pricing legislation for intra-group services. South Africa’s transfer pricing legislation for intra-group services will be compared to Aligning Transfer Pricing Outcomes with Value Creation, Action 8-10, 2015 Final Reports, OECD/G20 Base Erosion and Profit Shifting Project (‘BEPS Action Plan’) released by the Organisation for Economic Co-operation and Development (‘OECD’). The Action 10 of the BEPS Action Plan introduces a simplified transfer pricing approach for low value-adding intra-group services. The simplified approach aims to reduce base erosion payments through excessive management fees and head office expenses (OECD, 2015:141). According to Verlinden and Katz (2015:1): ‘… the simplified approach lowers the burden on multinational enterprise groups to demonstrate the beneficial nature of the low value-adding activities for other MNE group members; and allows for an elective approach for reducing the administration involved in the pricing of low value-adding services. The OECD is achieving an appropriate balance between theoretical sophistication and practical application that is commensurate with the tax at stake in the countries paying and receiving the charges … .’ This approach will benefit tax authorities with limited resources in performing transfer pricing audits enabling them to verify the arm’s length nature within the intra-group services charge (Watson, 2015:8).

This paper aims to critically evaluate the current South African legislation and the obligations it places on financial institutions. The research also highlights the challenges faced by a financial institutions in interpreting and implementing the often complex requirements of the regulations with a particular focus on the following areas namely customer on-boarding and enhanced due diligence procedures, monitoring of accounts, remediation of the existing customer base, system development, and reporting to the South African Revenue Service. The research also looks into the readiness of developing countries in implementing the Automatic Exchange of Information. The research concludes with a discussion into the appropriateness of South Africa’s decision to agree to be one of the early adopters of this legislation despite the challenges identified above.
