  • Description: Discovering and developing one’s talents significantly increases the likelihood of one leading a meaningful and fulfilling life, realising success in the world, and breaking out of the cycle of poverty. It should be the responsibility of schools to provide opportunities for learners to discover and develop talents that they are passionate about. This passion will then create a self-reinforcing cycle in which learners are more motivated to work hard in school and further develop their talents. Therefore, discovering and developing one’s talents should be seen as both a means to improved education and an end of education itself. This research paper sought to identify the factors limiting township learners from discovering and developing their talents and to make recommendations as to how to mitigate these factors. The researcher used the partnership between the Masinyusane Development Organisation, a local education non-profit organisation, and School A, a secondary school in the township of New Brighton, Port Elizabeth as a case study. Data from the study were carefully analysed and it was concluded that the township learners are not being provided the opportunities necessary, particularly in the schools, to discover and develop their talents. This has resulted in poor academic performance, high drop-out rates, low levels of motivation, confusion with regards to career development, and missed opportunities to break out of the cycle of poverty. The researcher believes this research sheds light on the issue and lays a foundation from which to provide South African township learners with greater opportunities to discover and develop their talents. These opportunities will assist learners in improving their school performance, ensuring that they embark on career paths they will realize success in, and ultimately, in breaking out of the cycle of poverty that traps so many of them.

  • Description: This study examines the socio-economic impact of fair trade on black emerging citrus fruit farmers in the Eastern Cape Province of South Africa. It is a comparative analysis of farmers involved in fair trade and those who are not. Farmers from Riverside Enterprise and Sundays River Citrus Cooperative were examined to evaluate the impact of fair trade. Such impact was analyzed through looking at access farmers have to foreign markets and their ability to receive high income returns from these markets. The study also discusses the influence fair trade has on the social and economic development of the farmers’ communities. The findings of the study indicate how most fair trade communities have benefited financially and through public infrastructure such as crèches, learning centers and access to computers for both farmers and workers. Such public developments are funded through the fair trade social dividend which is a premium farmers receive for selling their fruit under fair trade. However, the study findings also indicate the limitations of fair trade; farmers have to incur high costs to become fair trade accredited. The study also examines the commodity value chains (hereinafter referred to as CVC) for citrus fair trade farmers and non fair trade farmers. This analysis reveals the procedure of value chains, their benefits and constraints.

  • Description: The long-beaked common dolphin, Delphinus capensis (Gray 1828), is one of the most enigmatic predators feeding in the annual sardine run (Sardinops sagax) off the coast of KwaZulu-Natal (KZN), South Africa. In recent years, unpredictable inter-annual variations in the timing, spatial extent and intensity of the sardine run have been documented, possibly resulting in changes in the suite of prey available to the common dolphin during winter. Although the diets of a number of predators during the sardine run have been studied in detail (e.g. sharks and flying seabirds), little is known about the diet of long-beaked common dolphins during this period. Each year, a low number of common dolphins are incidentally caught in the anti-shark nets in the waters of KwaZulu-Natal. These captures provide a valuable source of data on selected aspects of the ecology of the long-beaked common dolphins along the KwaZulu-Natal coastline. The objective of this study was to provide new dietary data for the common dolphins feeding in the waters of KwaZulu-Natal during winter over the period 2000 to 2009, as well as to determine if any dietary changes had taken place since the common dolphin diet was last assessed, over 15 years ago. Stomach contents from 95 common dolphins (55 females, 40 males) caught between 2000 and 2009 were analysed and compared to historical data from dolphins caught between 1974 and 1992. Mesopelagic fish and squid dominated the diet, with 23 fish and 5 squid species represented in adult dolphins. Multidimensional Scaling (MDS) indicated that there was no resource partitioning between adult male and female dolphins. Numerical analyses indicated that there was a shift in the principal prey species consumed by the dolphins over the past decade, particularly during the winter. Prior to 1992, sardine comprised up to 49% of the total stomach contents, while chub mackerel (Scomber japonicus) was the dominant prey item (66% by mass) recorded in the stomach contents over the period 2000 to 2009. The shift in the relative contributions of sardine and mackerel in the diets of the dolphin appeared to correspond to fluctuations in the availability of the two principal prey species. Between 2000 and 2009, the diversity of the dolphins' diets was highest during the sardine run, reflecting the presence of a wide suite of predatory teleosts in the waters of KwaZulu-Natal during the annual sardine run. Conversely, prior to 2000, the diet was dominated by sardine during the peak of the sardine run, whilst diet diversity increased after this period. Apart from sardine and chub mackerel, elf (Pomatomus saltatrix), maasbanker (Trachurus delagoa), strepie (Sarpa salpa) and flying fish (Exocoetid sp.) also formed important components of the diet both prior to 1992, and over the last decade. Blubber thickness was assessed as an indicator of animal condition. No significant change in blubber total weight (R² = 0.0016, N = 185), nor dorsal, lateral or ventral blubber thickness (R² = 0.3146, R² = 0.0003, and R² = 0.0003 respectively, N = 78) was seen over the last 30 years (1970 to 2009). Results of stable isotope analyses conducted on tissue derived from the teeth of D. capensis indicated that there has been no significant shift in the trophic position (δ¹⁵N) and potential prey consumed (δ¹³C) over the corresponding period. These data would suggest that the long-beaked common dolphins along the KwaZulu-Natal coastline can be considered as opportunistic predators generally consuming the most abundant prey species available locally. As common dolphins feed opportunistically, this dietary shift appears to indicate changes in the shoaling characteristics of the most abundant fish prey in KwaZulu-Natal during winter. Given the “Data Deficient” status of the long-beaked common dolphin on the IUCN Red Data List, and the strong climatic forcing of the sardine run, such dietary data have important implications for their conservation in the light of expanding fisheries and climate change.

  • Description: According to Lewis Seifert, “Fairy tales are obsessed with femininity … These narratives are concerned above all else with defining what makes women different from men and, more precisely, what is and is not acceptable feminine behaviour” (1996: 175). This study, then, will demonstrate how certain patriarchal ideas associated with fairy tales are disseminated when fairy tale elements are reworked in film, visual art and the novel. The aim of this project, more specifically, is to show how certain stereotypical representations of women endure in works that could be read as feminist appropriations of Hans Christian Andersen’s ‘The Little Mermaid’. Stereotypical representations of women are numerous and may include: depicting females as fitting neatly into what is often called the virgin/whore or Madonna/whore binary opposition; depicting women as being caring and kind, but also passive, submissive and weak; and depicting older women as being sexually unattractive and evil (Goodwin and Fiske 2001:358; Sullivan 2010: 4). It must be said that the list of stereotypes relating to women given here is far from exhaustive.

  • Description: Georges Duby and Michelle Perrot’s work, Histoire des femmes en Occident, Antoine Prost and Gérard Vincent’s work A History of Private Life as well as Chantal Antier’s work Les Femmes dans la Grande Guerre and Carol Mann’s work Femmes dans la Guerre, show that women have been largely ignored in the annals written about the twentieth century. This period was one marked by two World Wars, which had an enormous impact on women, especially in terms of their roles in society. These events resulted in women moving from the home to the world of work. These writers acknowledge that women in the twentieth century were mostly excluded from history. In contrast to others who have written about this time, these writers consider women and their roles in society and how these roles have changed as a consequence of the historical events of the time. Marie-Paul Armand was a popular writer of French fiction. At first glance her novels seem to be enjoyable historical, romantic fiction for readers who enjoy sentimental love stories. However on closer examination one can see that she rigorously researched the period in which her novels are set. These novels reconstitute the reality of women’s lives during the twentieth century. In her first award-winning novel La poussière des corons, Armand depicted the life of her main character, Madeleine, through the various stages of a woman’s life from her birth at the turn of the century, early childhood, adolescence during the First World War until old age in the 1960s. This novel mirrors the life of a woman in working class French mining society from the beginning of the twentieth century until the fifties and sixties when Western women underwent an unprecedented metamorphosis of their role. These novels would appeal to a wider readership than works by Historians with the same subject matter.

  • Description: This dissertation examines Elias Canetti‟s novel, Auto-da Fé, in an attempt to show how it depicts the manifestations of violence and the effects of traumaon the individual and on modernist society. This analysis of Auto-da Fé concentrates on the representation of trauma on a fictional level at a time when Europe was experiencing political, social and economic upheaval after the First World War. Auto-da Fé provides an intense emphasis on the psychological effects of trauma on the characters; thereby reflecting the turmoil of this period. An analysis of Canetti‟s novel, in the light of trauma, reveals an enigmatic testimony not only to the nature of violent events, but of the way trauma resists simple comprehension. I argue that this gives rise to complexities within the narration by tracing the insistently recurring words and symbols which point to an interpretation beyond the thematic content of the text, namely one which repetitively bears witness to hidden wounds within individual consciousness. The titles of the three parts of Auto-da-Fé reflect a condition of somatic and sychosomatic dislocation: “A Head without a World”, “Headless World”, and “The World in the Head”. My argument is that the fictional trauma in Canetti‟s novel contains several characters who suffer from a breach of the self and the inability to comprehend society. The inability to fit into society results in the protagonist creating an isolated refuge in order to protect himself from the outer world. However, his alienation exacerbates his physical and emotional dislocations and ultimately leads to his destruction.

  • Description: The successful launch of the European Monetary Union (EMU) raised an already ever growing interest in the economics of monetary integration and the formation of monetary unions around the world. Following the EMU experience, countries have considered forming a monetary union amongst themselves. The East African Community (EAC), comprising the three original member countries Kenya, Tanzania and Uganda and now including Burundi and Rwanda, is an example of such a group of countries that seek to form a monetary union. This study aims to identify the current level of financial integration amongst the East African countries. In order to do so the study examines whether the pass-through of monetary policy in the five countries has become similar over time. This is to provide an indication of the extent to which the nominal convergence criteria amongst the member countries have been met. The results of the study provide an indication of whether the formation of a monetary union in East Africa is possible. The empirical analysis used in this study included stationarity tests, four tests of co integration and an asymmetric error correction model to investigate whether the pass-through of monetary policy transmission in the five countries has become more similar over the ten year sample period from 1999 to 2008. The analysis uses three interest rates and 6-year rolling windows to identify the extent of macroeconomic convergence that prevails within the EAC, and consequently whether the formation of a monetary union is possible. The results suggest that the magnitude of the convergence amongst the countries remain low and there are significant rigidities in the deposit and lending rates over time, however the passthrough has improved with respect to the lending rate but not the deposit rate. The overall conclusion of the study suggests that an EAC wide monetary union is currently not possible based on the evidence provided from the pass-through analysis.

  • Description: Financial systems (i.e. banking systems and stock markets) can influence economic growth by performing the five key financial functions, namely: mobilising savings, allocating capital, easing of exchange, monitoring and exerting corporate governance, as well as ameliorating risk. The level of development of the financial system is a key determinant of how effectively and efficiently these functions are performed. This study examines the short-run and long-run relationships between financial system development and economic growth for a panel of seven African countries (namely: Egypt, Ivory Coast, Kenya, Morocco, Nigeria, South Africa and Tunisia) covering the period 1988 to 2008. While numerous empirical studies have researched this topic, none of the previous African empirical literature have investigated thjs by using three groups of financial development measures (i.e. overall financial development, banking system development and stock market development measures) as well as employing panel cointegration analyses. The investigation of the long-run finance-growth relationship is conducted using two methods; the Pedroni panel cointegration approach and the Kao panel cointegration technique. The Pedroni panel cointegracion approach is more often applied in empirical research as it has less restrictive deterministic trend assumptions, while the Kao panel cointegration technique is employed in this study for comparison purposes. Furthermore, the short-run linkages bet\veen financial development and economic growth are analysed using the Holtz-Eakin d of (1989) panel Granger causality test. The results of the Pedroni cointegration tests show that there are long-run relationships between overall financial development (measured by LOFD and OFD2) and economic growth, banking system development (measured by LPSC) and economic growth, as well as stock marker development (measured by LMCP and LVLT) and economic growth. In contrast, the Kao test fails to find any cointegration between finance and growth. However, on the balance, findings largely support a conclusion of cointegration between financial development and economic growth since the Pedroni approach is more appropriate for examining cointegration in heterogeneous panels. Estimates of these long-run cointegrating relationships show that all five financial development measures have the expected positive linkages with growth. However, only four of the five financial development measures were found to have significant long-run linkages with growth, as the relationship between LOFD and growth was not found to be significant in the long-run. The panel Granger causality results show that economic growth Granger causes banking system development in the short-run (i.e. there is demand-following finance), irrespective of the measure of banking development used. While there is bi-directional, reciprocal causality between economic growth and both of the measures of overall financial development and one measure of srock market development (i.e. LVLT). Thus, pulicy makers should focus on formulating policy which promotes faster paced economic growth so as to stimulate financial development, while at the same time encourage policy that promotes the balanced expansion of the banking systems and srock markets in ordet to augment economic growth.

  • Description: The work in this dissertation deals with the global structural response and local damage effects of a simply supported natural fibre composite sandwich beam subjected to a four-point bend. For the global structural response, we are investigating the flexural behaviour of the composite sandwich beam. We begin by using the principle of virtual work to derive the linear and nonlinear Timoshenko beam theory. Based on these theories, we then proceed to develop the respective finite element models and then implement the numerical algorithm in MATLAB. Comparing the numerical results with experimental results from the CSIR, the numerical model correctly and qualitatively recovers the underlying mechanics with some noted deviances which are explained at the end. The local damage effect of interest is delamination and we begin by reviewing delamination theory with more emphasis on the cohesive zone model. The cohesive zone model relates the traction at the interface to the relative displacement of the interface thereby creating a material model of the interface. We then carry out a cohesive zone model delamination case study in MSC.Marc and MSC.Mentat software packages. The delamination modelling is carried out purely as a numerical study as there are no experimental results to validate the numerical results.

  • Description: Unemployment is one of the greatest and most complex challenges facing South Africa. Just like most developing countries, South Africa has been using the fiscal policy framework as a tool to alleviate the high rates of unemployment. This study examined the impact of fiscal policy on unemployment in South Africa. The study used annual time series data for the period 1980 to 2010. A vector error correction model was used to determine the effects of fiscal policy aggregates on unemployment in South Africa. The fiscal policy aggregates considered in this study were government investment expenditure, government consumption expenditure and tax. Results from this study revealed that government consumption expenditure and tax have a positive impact on unemployment while government investment expenditure negatively affects unemployment in South Africa. Policy recommendations were made using these results.

  • Description: Molecular thin films of manganese (SAM-2), iron (SAM-3), and cobalt (SAM-4) phthalocyanine complexes, non-peripherally tetra-substituted with benzylmercapto, were formed on polycrystalline gold disc electrode by self-assembly technique. Surface characteristics of the films were interrogated by cyclic voltammetry. Significant passivation of voltammetry processes associated with bare gold surface (gold oxidation and underpotential deposition of copper) confirmed formation of the films. Electrocatalytic property of the films was evidenced from better voltammetry responses (less positive oxidation potential and better current signal) of the insecticide, carbofuran, on these films, relative to that on bare gold electrode. In terms of less positive oxidation potential, the FePc derivative (3) gave the best response, while the best current signal was observed on SAM-2-modified gold electrode. The average heterogeneous rate constant, k, for the oxidation of carbofuran was 3.6 × 10−2 cm s−1 on the SAM film with the best current signal (SAM-2).

  • Description: The purpose of this article was to investigate the feasibility of incorporating didanosine (DDI) into nanostructured lipid carriers (NLC) for potential treatment of AIDS dementia complex. Aqueous DDI-free and DDI-loaded NLC were manufactured using hot high-pressure homogenization. The lipid matrix contained a mixture of Precirol ® ATO 5 and Transcutol ® HP. Photon correlation spectroscopy revealed that the mean particle size for all formulations was below 250 nm with narrow polydispersity indices. In addition, the d99% values for all formulations determined using laser diffractometry were below 400 nm with the span values ranging from 0.84 to 1.0. The zeta potential values ranged from −18.4 to −11.4 mV and the encapsulation efficiency of NLC for DDI ranged from 33.02% to 78.34%. These parameters remained relatively constant for all formulations tested following storage for 2 months at 25°C indicating that all the formulations were relatively stable. Differential scanning calorimetry revealed a decrease in the degree of crystallinity of NLC in all formulations developed relative to the bulk lipid material. In addition, wide-angle X-ray scattering showed that NLC in all formulations tested existed in a single β-modification form and that DDI that had been incorporated into the NLC appeared to be molecularly dispersed in the lipid matrices. Images of the NLC formulations obtained using transmission electron microscopy revealed that all formulations contained a mixture of spherical and nonspherical particles irrespective of the amount of DDI that was added during the manufacture of the formulations.

  • Description: The use of mobile phones and other mobile devices are becoming widespread and almost all of these mobile devices have some sort of mobile Internet access. Due to the increase in mobile Internet usage, many websites need altering in order to become mobile compatible. Creating a mobile compatible version of a website is challenging due to formatting and capability restrictions imposed by the mobile device. Currently, one of the popular methods of creating a mobile compatible website involves the creation of a new, dedicated mobile version of the website. However, this approach can prove to be expensive, and repetitive, since a fully functional desktop version of the website often already exists. A second method involves the use of a transformation proxy to transform the traditional website into a mobile compatible version. This research develops a transformation framework that enables a web developer to create a single set of source files that can be used to render output compatible with both traditional and mobile devices. In developing this framework, capabilities and restrictions of the mobile device were examined. Furthermore, current mobile web development guidelines and best practices were discussed. This resulted in the development of a method to identify and outline areas of a traditional website for transformation into a mobile friendly format. Furthermore, a transformation engine that allowed processing of the traditional website into a mobile compatible website was developed. This transformation engine extracted the outlined areas, and rendered the extracted content, all while maintaining the website’s original functionality. The development of a prototype verified that the transformation concepts are valid, and provided for the development of guidelines and recommendations. The development of a framework to enable the web developer to create a website once, and enable it to adapt its output for mobile devices, will have a positive impact on the development of content for the mobile web.

  • Description: Oral traditions and oral literature have long contributed to human communication, yet the advent of arguably the most influential technology—the written word—altered the course of creative ability. Despite its potential and scope, the development of the written word resulted in an insidious dichotomy. As the written word evolved, the oral word became devalued and pushed to the fringes of society. One of the unfortunate consequences of this transition to writing has been a focus on the systems and conventions of orality and oral tradition. Although of importance, a more appropriate focus would be on ways of supporting and maintaining the oral word, and its innate value to human society, in the face of rampant technological development. Yet it is ironic that technology is also helping to create a fecund environment for the rebirth of orality. This paper offers an overview of the debate about the relationship between oral literature, the written word and technology, and suggests that the term technauriture may offer a suitable encompassing paradigm for further engagement with the oral word and its application to modern society. We discuss the late Bongani Sitole, a poet whose oral works were transformed into public and educational resources through the application of technology, and we consider the utility of the term technauriture for describing the relationship between orality, literature and technology.

  • Description: Numerous studies exist examining the link in solo singers between timbre and overtone spectra. The purpose of this study is to examine if similar results can be obtained by applying the same techniques to choral singing. The study is aimed at non-scientific readers and therefore introduces the subject with background to the relevant physics. In this study a number of recorded samples of choirs were taken from www.youtube.com and analyzed. The analysis included computation of long-term average spectra (LTAS) and singing power ratio‟s (SPR), which provided an indication of the relative energy in the higher overtone region of every choir. This was compared to a binary value judgment of the choirs. The results indicate that the SPR as applied to soloists cannot be directly applied to choirs. A link between SPR and a perceived “good” choral tone could exist but would have to be interpreted differently than in the case of soloists. It was also found that a possible link could exist between frequency peaks in LTAS and a choir‟s intonation.

  • Description: Numerous studies exist examining the link in solo singers between timbre and overtone spectra. The purpose of this study is to examine if similar results can be obtained by applying the same techniques to choral singing. The study is aimed at non-scientific readers and therefore introduces the subject with background to the relevant physics. In this study a number of recorded samples of choirs were taken from www.youtube.com and analyzed. The analysis included computation of long-term average spectra (LTAS) and singing power ratio‟s (SPR), which provided an indication of the relative energy in the higher overtone region of every choir. This was compared to a binary value judgment of the choirs. The results indicate that the SPR as applied to soloists cannot be directly applied to choirs. A link between SPR and a perceived “good” choral tone could exist but would have to be interpreted differently than in the case of soloists. It was also found that a possible link could exist between frequency peaks in LTAS and a choir's intonation.

  • Description: Given their widespread effects and distribution in both natural and industrial environments, the monitoring of phenolic compounds is of considerable analytical interest. Electrochemical biosensor technologies, in particular those comprising laccase enzymes, afford many potential benefits to address this analytical need. However, several key factors affecting sensor response currently limit their applicability. This Thesis reports on the fabrication and optimisation of an electrochemical laccase-based biosensor towards the application of the monitoring of phenolic compounds. Selected factors considered to affect sensor response were investigated using the optimised biosensor. These included: electrochemical, biochemical and substrate-dependent factors, which were found to intersect in modulating biosensor response signals. Through the application of transducer-dependent and substrate-dependent parameters, the selective and simultaneous detection of a mixture of different phenolic analytes is successfully demonstrated. This Thesis also investigates the use of Quartz-Crystal Microbalance with Dissipation (QCM-D) technology, an analytical technique that measures physical parameters of thin-film structures, towards the successful monitoring of enzyme immobilisation strategies. These strategies are fundamental to the successful fabrication of biosensors, and the real-time monitoring of immobilised film formations is of considerable research interest. In the studies reported on in this Thesis, QCM-D technology was demonstrated to be an effective complementary technology in the prediction of film immobilisation techniques on the resultant biochemical kinetics of immobilised enzymes.

  • Description: This study consists of a comparative analysis of three novels by three prominent African women writers which cast light on the ways in which women are oppressed by traditional and cultural norms in three different African countries. These three primary texts also explore the ways in which African women‟s lives are affected by other issues, such as colonialism and economic factors, and this study discusses this. An analysis of these novels reveals that the interconnectedness of racial, class and gender issues exacerbates the oppression of many African women, thereby lessening the opportunities for them to attain self-realization. This study goes on to investigate whether there are possibilities of empowerment for the women in the primary texts, and examining the reasons why some women fail to transcend their situations of oppression. The primary novels will be discussed in different chapters, which explore the problems with which various women are beset, and discuss the extent to which the various women in the novels manage to attain empowerment. In conclusion, this study compares and contrasts the ways in which the women in the primary texts are oppressed and highlights the reasons why some women are able to attain empowerment, whilst others are unable to do so. It also shows that many women are beset with comparable forms of oppression, but they may choose to react to these situations differently. Over and above these issues, the study seeks to draw attention to the fact that women need to come together and contribute to the ways in which they can attain various forms ofempowerment.

These three primary texts also explore the ways in which African women's lives are affected by other issues, such as colonialism and economic factors, and this study discusses this.
