- Description: Extensive research has been done on the relationship between financial development (FD) and growth (with the main focus on economic growth). Theoretical models and most of the conclusions reached stipulate that the development of a financial system is one of the essential ingredients for economic growth. A developed financial system is able to provide financial services efficiently to the real sector. This study examines the relationship between FD and manufacturing sector growth of the SACU countries. The study first reviews the theoretical and empirical literature of FD and growth (economic and manufacturing sector). This gives a full understanding of the topic before attempting to empirically study it. It also helps in the selection process of the model and variables to be employed in the study. A balanced panel for four SACU countries, namely Botswana, Lesotho, RSA and Swaziland, for the period 1976 to 2008 was estimated using Zellner‟s Seemingly Unrelated Regression Estimation (SURE) method. Namibia was omitted because of limited data. The SURE model was selected because it performs better than ordinary least squares (OLS) estimation of individual equations in cases where the countries studied can be affected by similar external shocks because they are in the same economic region and also have country specific structural differences which could affect their economic growth. Two measures of FD were used: credit to the private sector provided by commercial banks (FIC) and the ratio of liquid liabilities of commercial banks to GDP (LL). Manufacturing sector growth was measured by manufacturing value added to GDP. The results of the relationship between manufacturing growth and FD were very weak across the countries. The model that used FIC performed better, there was a negative significant relationship found in RSA and Swaziland, while with the model that used LL, all the countries gave an insignificant relationship. The results for Swaziland were very consistent with the past findings of the relationship between FD and economic growth in the country (for example Aziakpono (2005a)). This may be because of the high share of the manufacturing sector in GDP. Theory suggests that a well-developed financial system will have a positive impact on growth, but this was not the case in RSA and Botswana, where in some cases FD had a negative impact on the growth of the sector. The analysis of the countries‟ manufacturing sector development shows that the sector plays an important role in the economies of the SACU countries, especially in terms of employment and exports. The coefficients of trade openness are generally positive, though not significant in some cases. The other control variables gave mixed results across the counties and across the models. Based on the findings, the countries have to develop strategies that will improve entrepreneurial skills. Also the financial development in the small SACU countries is essential in order for all the sectors in the economy to benefit from the financial sector and in turn increase economic growth.

- Description: “Academic freedom” does not mean the same thing to everyone. There are, to be sure, a few who argue against it. Sandra Korn, in the Harvard Crimson last year, argued that we should abandon academic freedom in favor of academic justice. She argues that we have reached a consensus on issues such as racism, classism and sexism, and so to promote racist or classist or sexist views under the guise of “academic freedom” is to ignore a higher standard and more importantly to ignore the fact that academic freedom is always couched in political realities, and is never the dispassionate exercise of reason and the pursuit of knowledge. It always serves an agenda, and so if that is the case, it should serve the agenda of justice, particularly justice for disadvantaged and marginalized people. Her online article, when I last looked, had almost 1300 comments, and had inspired commentary from a number of other publications. You can imagine the range of these comments and reactions: everything from “this is long overdue” to the newest favorite insult circulating the internet, “she’s just another Social Justice Warrior (SJW).”

- Description: The use of the yield curve in forecasting economic recessions is well established in the literature. A new avenue of use for the yield curve has emerged in the form of using it to forecast bull and bear stock markets. This has the potential to change how investors manage portfolios. A dynamic market-timing strategy would allow investors to shift out of or in to stock markets based on the probability of bear stock market in the future. The relationship between the yield curve and the stock market is tested using an adapted probit model. This has proven positive with encouraging results for the US, India and Spain. This is tested for South Africa using the adapted probit model and the SA yield spread. Bear stock markets are identified on the JSE and forms part of the probit modelling process. Bear markets are identified using a six- and four-month criteria. As South Africa is a small, open and developing economy, the probit is also modelled using the US yield spread. The three probit models do not appear to track bear markets well. This is substantiated through the Henriksson-Merton parametric model test which tests for market timing ability. The results for the SA yield spread using both bear market criteria do not show market timing ability, however, the SA and US yield spread model does show potential market timing ability.

- Description: Early stage fishes (larvae and early juveniles) were collected from an array of shallow water (±1.5m) habitats on the warm-temperate southern Angolan coastline between June 2014 and June 2015. This study, the first assessment of the early stages of coastal fishes in Angola, provides important new understanding of non-estuarine shallow water nursery habitat use by coastal fishes from the region. In total, 51 species from 18 teleost families were observed. The exposed surf zone was dominated by postflexion larvae, while the moderately exposed beach and sheltered bay were dominated by early juveniles. Both fish density and diversity peaked in the wet season (Feb – Apr 2015) for all habitats, attributed to the influx of summer spawning species. Diplodus sargus dominated catches from the exposed surf zone, and the timing of observations supports the growing consensus that sparid spawning is dictated by temperature, not season. The similitude of the observed species to those observed in warm temperate South Africa highlights the historical connection of the warm-temperate study area with warm-temperate South Africa, prior to the formation of the Benguela Current as a vicariant barrier. The classification of the study assemblage into established estuarine utilization categories showed that the surf zone hosted more exclusively marine species than comparable surf zones in South Africa, attributed to the absence of estuaries in southern Angola. However, the observation of the marine estuarine dependent Mugil cephalus in this study area devoid of estuaries suggests that estuarine dependency may be regionally specific for some taxa. It appears that the warm, sheltered, nutrient rich waters of Tombua Bay provide typically estuarine associated taxa with a suitable alternative, non-estuarine nursery habitat. This study provides evidence that the importance of estuaries as critical nursery habitats has been overemphasized for some warm-temperate coastal fishes. However, the absence of other marine estuarine dependent species from the study area suggests that some warm-temperate taxa do intrinsically rely on estuarine function for survival.

- Description: The periodicity of formation of growth increments in the otoliths of South African sparids was validated by the oxytetracycline labelling technique. Intramuscular injections of oxytetracycline at a dosage of 250mg/kg marked the otoliths of laboratory held juvenile sparids, while a dosage range of 50 - 100mg/kg oxytetracycline, injected intramuscularly, marked adult sparids in the field. Laboratory held, larval sparid otoliths were marked by immersion for 24hrs a solution of 100-150mg/l alizarin complexone. Both daily (microstructural) and annual (macrostructural) growth increments were identified in the otoliths. The micro incremental pattern of deposition in the sparid otoliths conformed to the general pattern of otolith structure. Sparid otoliths consisted of a central opaque nucleus composed of multiple primordia. surrounding this nucleus were daily increments which decreased in width as the distance from the nucleus increased. Both check rings and subdaily increments were visible throughout the otolith. Minor environmental changes did not affect micro incremental deposition. Narrow opaque and wide hyaline annual growth zones were identified in sectioned sparid otoliths. Scanning electron microscope analysis of the annual growth zones revealed that microincrements within the opaque zone were narrowly spaced with prominent discontinuous phases. This resulted in the greater optical density and higher protein content of the zone. The hyaline zone was composed of widely spaced daily increments with prominent incremental phases accounting for the translucent nature of this zone. Opaque zone formation in the otoliths of many South African sparids was found to occur primarily during periods of reproductive activity and was shown to be indicative of slow otolith growth. The hyaline zone was formed after the spawning season, representative of fast otolith growth. The results of this study have resolved much of the controversy surrounding the rate of growth and time of formation of the opaque and hyaline growth zones in South African sparid otoliths.

- Description: The African Coelacanth Ecosystem Programme (ACEP) was established in 2002 after the discovery of a colony of coelacanths off the Maputaland coast at Sodwana Bay, KwaZulu Natal. The environmental education and awareness sub-programme developed learning support materials (LSM's) for use in schools and the materials were disseminated annually through teacher education workshops. This study aimed to uncover the use of these LSM's in the rural schools of Maputaland. The active learning framework was used to analyse the materials. Collectively, the ACEP materials cover a range of active learning aspects; however alignment with the curriculum has resulted in an increased focus on experiments, accompanied by a loss of environmental content and a narrowing scope for active environmental learning. Workshop questionnaires and four school case studies revealed the patterns of practice of use of materials in schools. The stated use of materials by teachers is not fully realized in the actual classroom practice which centres on learning content and concept definitions. There is no culture of use of materials in the schools following the annual introduction of ACEP materials. It was also found that the marine and coastal knowledge holding power is outside the realm of the teachers' practice and control. The findings of this study come at a time when there is uncertainty over the future of South African education and the curriculum. This research may inform the environmental education and coastal and marine education field as to their role in education and more specifically the development of learning support materials.

- Description: Introduction: At first glance, darkness is merely the absence of light, and is therefore negative; hence the traditional equation of night with death, evil and the creatures of the underworld. But a closer study will reveal that darkness is also a positive force; examples can be cited from various cultures where darkness was thought to have given birth to light. The subterranean is the realm of fertility; the worshippers of Dionysius realised this, as did the followers of the world-wide cult of the Great Earth Mother. The realm of darkness is also the habitat of the mystic. In this essay, we will attempt to define the nature of nocturnal imagery, and to trace the various ways in which mankind has sought to reconcile himself with the powers of darkness.

Apart from the provision of a valuable tanning extract for home use and for export, the tree itself has proved of considerable importance to the Union’s mining industries. In addition there would appear to be possibilities for the utilisation in the near future, of the raw ground bark and the wattle extract for the manufacture of a number of by-products, including certain types of plastics.

- Description: The Fourth Industrial Revolution (4IR) is set to disrupt existing economic and social structures through the use of cyber-physical systems that result from a fusion of the digital, biological, and physical spheres. The fifth and current long wave of innovation is going through such a digital revolution in the ongoing deployment period which is being driven by the generalpurpose technologies of Artificial Intelligence and the Internet of Things, among other cyberphysical systems. The impact of mobile money in the access of financial services has shown how disruptive incremental innovations in mobile and digital technologies can be. The transformational power of mobile money in financial access is due to its use as an accessible financial tool that utilizes mobile devices to send and/or receive money over great distances. With the 4IR looming, this thesis determines the factors that enable and constrain the adoption of a disruptive technology amongst Sub-Saharan African small, micro, and medium enterprises (SMMEs). Therefore, due to its impact on financial inclusion and the formalization of SMMEs, mobile money is used as an indicator for the adoption of 4IR disruptive digital technologies. The adoption of mobile money was evaluated using secondary data from a survey conducted by Research ICT Africa, which surveyed 4408 SMMEs in nine African countries. The Diffusion of Innovations (DOI) model and the Unified Theory of Acceptance and Use of Technology (UTAUT) model were used to identify the factors enabling and constraining the adoption of a disruptive technology, in this case mobile money. Factors included gender, vocational training, business skills training, tertiary education, services, performance expectancy, social media, location, and nine African countries (Kenya, Mozambique, Ghana, Nigeria, Rwanda, South Africa, Tanzania, Uganda, and Senegal). The factors were grouped into owner characteristics, firm attributes and country attributes. SMME owners with business skills (49%) showed the highest level of adoption in terms of owner characteristics, Kenyan SMMEs (21%) had the highest adoption between the countries surveyed, and social media (62%) showed the highest adoption in terms of firm attributes followed by the formal variable (47%). In general, only 29% of SMMEs surveyed adopted mobile money. The study found that women SMME owners were more likely to be affected by business formality when adopting a disruptive technology compared to male owned SMMEs. This is because informality often exacerbates other barriers/challenges women face such as lower access to finance, lower ability to exercise property, business, and labour rights, and lower visibility. The results also demonstrate that vocational training is more important than general tertiary education for the ii adoption of a disruptive technology such as mobile money. Furthermore, when using social media as a tool for business advice SMME owners were more likely to adopt the disruptive technology. The study suggests that to encourage African SMMEs to adequately adopt disruptive technologies of the 4IR, more women owned SMMEs need to enter the formal economy, and vocational training targeted at business skills must be promoted amongst all SMME owners. Eastern African SMMEs were found to be more likely to adopt mobile money compared to other African regions. The finding demonstrates the need for more African countries (particularly outside of the Eastern African region) to encourage innovation by addressing the four enablers of mobile connectivity (i.e. infrastructure, affordability, consumer readiness, and mobile services) which will in effect lead to economic growth and development. The study shows that to address country/regional differences, in addition to building the required infrastructure in terms of mobile internet connectivity, countries should increase the local relevancy of disruptive technologies between SMMEs. To achieve this the study suggests increasing mobile social media penetration rates. This is because when social media is used as a tool for business advice SMME owners are more likely to adopt a disruptive technology (as is the case with mobile money) due to the social influence of social media. , Thesis (MCom) -- Faculty of Commerce, Economics and Economic History, 2022

- Description: In this research the experience of pet loss in relation to the intensity of grief and the repression of that grief due to societal restrictions was studied in a South African sample of 12 pet owners who had experienced the loss of a pet within 24 months prior to the study. A pilot study was conducted in order to refine the semi-structured interview schedule. Participants were asked about their pets, their experience of pet loss in relation to their feelings before and after the loss and whether they felt they could openly grieve around friends and family. The findings indicated that the intensity of grief experienced by the participants was influenced both by the intensity of their Bond with the pet and the repression of their grief due to assumed social sanctions surrounding mourning the loss of a pet. The findings from the study clearly indicate the necessity for pet loss counselling, however it was clear that societal views surrounding pet loss are shifting, thus allowing pet owners to mourn their loss more openly with family and friends. This indicates a decrease in cases of disenfranchised and complicated grief. Furthermore the impact of pet loss necessitates the social legitimation and acknowledgment of the significance of pet loss in contemporary society as these relationships with pets are an increasingly prominent feature both within and as an alternative to familial systems.

- Description: This study deals with the problems of external examining, the inflexible demands of which dominate and dictate to literature teaching in South African schools today. The aims of teaching literature are discussed, and it is suggested that the negative attitudes among pupils resulting from the present examining system defeat many of these aims. The opportunities for the enjoyment of literature are minimised by the process of preparation for external examinations. Creative teaching methods are abandoned in favour of coaching for specific types of questions, which are determined and limited by the practical constraints of a mass external examination. In catering to the demands for admininstrative reliability and efficiency, the educational validity and efficiency of the examinations are sacrificed. In Britain the Newbolt and Bullock Reports, among others, have made forceful recommendations for alternative approaches to external examining. Subsequently, much experimentation with internal examining, course-work and open-book examining has followed, aspects of which are discussed in this study. There has been limited experimentation in these areas in South Africa. The TED conducted a successful internal examining experiment in English literature, the results of which are considered in this thesis. The national English Olympiad open-book examination is a further example of the success of an alternative approach. By contrast, a comparison of examination papers set by the JMB and CED over the last ten years, shows clearly that the stated syllabus aims of teaching literature and the aims of examining the subject were wholly incompatible. Recommendations are made for the adoption of alternative examining strategies in order to address the shortcomings identified

- Description: The South African wine industry is one of the oldest sectors of the country’s economy, beginning in the early years of South African colonialism in the 17th century through the use of slave and slave-like labour. As an industry that has been defined by farm paternalism and dependency, the South African wine industry has had to demonstrate changes from its history of extreme racial and gendered exploitation to an industry that reflects the democratic values of a new South Africa. Ethical certifications are considered one way through which the post-apartheid South African wine industry can demonstrate that it has moved away from its historical practices and is now characterised by practices of decent work and social transformation. An important certificatory label that allows local wine producers entry into global wine production networks is Fairtrade International. While Fairtrade certification is often reserved for small-scale producers, this certification has been extended to large-scale, commercial producers within the South African wine industry despite its history of farm paternalism and dependency. This research asks if this inclusion promotes decent work through social upgrading or if it offers a platform for the continuation of farm dependency under the guise of ‘Fairtrade’. In this study, social upgrading has been defined through a ‘bottom-up’ approach that prioritises workers’ independence as a key means of improvement. Four key pillars are applied as embodying the concept of social upgrading: regular employment with set working hours; legally enforceable worker rights; social protection through collective and individual bargaining power; and non-discriminatory social dialogue that promotes significant socio-economic progression. A key finding of this research is that practices of dependency and paternalism continue on some large-scale commercial farms, despite their Fairtrade certification. Furthermore, the findings suggest that the benefits that farmworkers receive lock farmworkers into their position on the farm with marginally improved conditions and cease if workers depart from the Fairtrade wine farm. This suggests that, at best, this inclusion of commercial farmers within Fairtrade certification appears to create a top-down form of social upgrading that locks farmworkers into their position on the farm with marginally improved conditions and beneath a glass ceiling of development. At worst, this Fairtrade inclusion facilitates a global poverty network through paternalism and dependency under the guise of ‘Fairtrade’. As a result, where meaningful, bottom-up social upgrading may occur on South African wine farms, the study suggests that this is despite the presence of Fairtrade and not a result of it. , Thesis (PhD) -- Faculty of Humanities, Political and Interntional Studies, 2022

Modelling stock return volatility dynamics in selected African markets

- Description: Stock return volatility has been shown to occasionally exhibit discrete structural shifts. These shifts are particularly evident in the transition from ‘normal’ to crisis periods, and tend to be more pronounced in developing markets. This study aims to establish whether accounting for structural changes in the conditional variance process, through the use of Markov-switching models, improves estimates and forecasts of stock return volatility over those of the more conventional single-state (G)ARCH models, within and across selected African markets for the period 2002-2012. In the univariate portion of the study, the performances of various Markov-switching models are tested against a single-state benchmark model through the use of in-sample goodness-of-fit and predictive ability measures. In the multivariate context, the single-state and Markov-switching models are comparatively assessed according to their usefulness in constructing optimal stock portfolios. It is found that, even after accounting for structural breaks in the conditional variance process, conventional GARCH effects remain important to capturing the heteroscedasticity evident in the data. However, those univariate models which include a GARCH term are shown to perform comparatively poorly when used for forecasting purposes. Additionally, in the multivariate study, the use of Markov-switching variance-covariance estimates improves risk-adjusted portfolio returns when compared to portfolios that are constructed using the more conventional single-state models. While there is evidence that the use of some Markov-switching models can result in better forecasts and higher risk-adjusted returns than those models which include GARCH effects, the inability of the simpler Markov-switching models to fully capture the heteroscedasticity in the data remains problematic.

- Description: A clinic survey was undertaken to investigate the nature of psychiatric problems experienced by the primary health care (PHC) patient population in the Bisho-King William's Town area of the Eastern Cape Region. The study took as its point of departure research findings which attest to the high rate of psychiatric distress amongst this population group in different parts of the world and ohservations regarding the form of presentation in terms of physical complaints. Hypotheses posited relationships between psychiatric problems experienced by patients attending PHC clinics in the study area and four types of variables, namely; somatic complaints, socio-demographic characteristics, patterns of health service utilisation and patient satisfaction with health services. Using a quasi-experimental descriptive approach, a two-stage screening procedure sorted the patient sample into three groups on the basis of the degree of psychiatric symptomatology experienced. The triangulation of the results of between-groups analyses with case materials recorded during psychiatric interviewing provided for an ethnographic account of the cultural experience of distress in the study area. The screening process used standard instruments, the Self-Reporting Questionnaire (SRQ) in the first stage and the Present State Examination (PSE) in the second stage. A pilot study was conducted prior to the fieldwork for the main study. Using the SRQ, thirteen psychiatric paticnts and 31 general PHC patients were sampled for the pilot study and 148 PHC patients were sampled for the main study. Using the PSE, 11 and 57 PSE interviews were conducted in the pilot and main studies respectively. Between-groups analyses used chi-square and F-statistics to investigate possible associations with identified patient correlates (P<0.5). These were socio-demographic, utilisation and satisfaction variables, measured by a separate face-valid self-response instrument compiled for the purposes of this study. Psychiatric symptomatology was found to be statistically significantly related to age, marital status and educational level. Further, patients experiencing more psychiatric symptomatology reported significantly more illnesses requiring treatment, longer consultation periods and a greater number of sick bed days. No statistically significant relationships were found between psychiatric symptomatology and number of children, number of failures at school, amount of treatment utilised, number of consultations, or patient satisfaction with services. Descriptive analyses of symptom and syndrome profiles found certain somatic complaints to be particularly prevalent amongst the patient sample. These include headaches and various tension pains, decreased energy levels and digestive problems. Qualitative analysis of interview data found that many somatic and psychiatric problems experienced constitute culturally defined and meaningful experiences, especially 'umbilini' (or nerves), 'ufufunyana' (a possession state), and accusations of witchcraft. Interpretation of complaints from the local traditional healing perspective, revealed a more complex mode of communication between patients and the health delivery system than may be accounted for in terms of a simple biomedical model. The interpretive analysis in the study showed that some forms of presentation incorporating somatic symptoms, such as 'nerves' may he viewed as help seeking behaviour of the socially unempowered. Implications of the results are discussed in relation to the need for improved identification and management of psychiatric distress at PHC level facilitated by a better developed referral network and closer interaction between biomedical and anthropological perspectives.

- Description: The nature of Internet and Intranet Web applications has changed from a static content-distribution medium into an interactive, dynamic medium, often used to serve multimedia from back-end object-relational databases to Web-enabled clients. Consequently, developers need to make an informed technological choice for developing software that supports a Web-based application for distributing multimedia over networks. This decision is based on several factors. Among the factors are ease of programming, richness of features, scalability, and performance. The research focuses on these key factors when distributing images from an Oracle9i database using Java Servlets, JSP, ASP, and ASP.NET as the server-side development technologies. Prototype applications are developed and tested within each technology: one for single image serving and the other for multiple image serving. A matrix of recommendations is provided to distinguish which technology, or combination of technologies, provides the best performance and development platform for image serving within the studied envirorunent. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in
