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: 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 article uses critical discourse analysis to discuss and analyse articles about rape that appeared in a South African newspaper, Grocott's Mail, between 14 October, 2008 and 29 October, 2009. Drawing on existing literature on “rape myths” in media coverage of rape, this article argues that Grocott's Mail perpetuates racial and gender stereotypes through the way in which it reports on rape. While not all of the articles included in the analysis use rape myths, most use one or more when discussing rape incidents. Specifically, Grocott's Mail tends to use rape myths that blame the victim for the rape and de-emphasise the role of the perpetrator in the rape.

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.

Description: The reflection of baseline isotopic signals along marine food chains up to higher trophic levels has been widely used in the study of oceanic top predators but rarely for intertidal predators. We investigated variation in the δ 13 C and δ 15 N ratios of a sedentary, rocky shore predator, the African black oystercatcher Haematopus moquini, over~ 2000 km of the southern African coastline, which is characterized by strong biogeographic patterns in primary productivity and intertidal communities. Blood and feathers from breeding adults and chicks and muscle tissues from primary prey items (mussels and limpets) were sampled between southern Namibia and the southeast coast of South Africa. 15 N enrichment was observed between the southeast and west coasts in oystercatcher tissues and their prey, mirroring an isotope shift between the oligotrophic Agulhas Current on the east coast and the eutrophic Benguela upwelling system on the west coast.

Description: The aim of this study is to examine key implementation and managerial issues surrounding the use of a Geographic Information Systems (GIS) as a Decisions Support Tool (DST) for planning and managing development interventions. Ever since the emergence of GIS as a powerful analytical tool in almost all spheres of human endeavour, many organisations involved in development work have adopted its use. But the challenges of conceiving and implementing a GIS in ways that are more responsive to the problems that trigger its purchase remains a daunting task to many development organisations; even those with a wealth of experience in GIS. This is one of the motivating factors for this study. In this research, some relevant themes in GIS implementation and GIS management as a Spatial Decision Support System (SDSS) were examined in the literature review. A case study research strategy was used focusing on the experience of the Nelson Mandela Bay Municipality Enterprise GIS (EGIS). The study examined how the system is been ran and what other development organisations can learn from this experience. Data was collected and analysed using a mixed research methods approach. The findings show a good level of GIS acceptance among municipality staff. However, running the system is not hitch free. A couple of problems and challenges were identified on the field. It is recommended that the municipality like most development organisations seeking GIS solutions should put the user at the centre of every technical innovation in GIS as a DST.

Description: This article discusses the role of privatization of security in Africa, but its focus is on private military and security companies (PMSCs). The article proceeds on the basis that there is need for effective regulatory frameworks for PMSCs that operate in conflict zones of Africa. Thus, it begins by appraising the existing normative standards at the international, regional and domestic level that apply to these companies, and thereafter, identifies their shortcomings in light of the prevailing security conditions within the continent. The article then posits broad theoretical imperatives for designing a more effective regulatory framework for PMSCs and concludes by proposing the establishment an overarching continental regime constructed on the basis of the suggested imperatives.

The study also aimed to control for the antecedents of group-based guilt and collective shame. Results revealed that guilt is predicted by perceived responsibility and is influenced by shame, while shame is predicted by image threat and guilt. The results further propose that the perceptions of status change for the ingroup and the outgroup predict the feelings of shame for high ingroup identifiers while status change (or lack thereof) for the ingroup predicts the willingness for symbolic reparation for low ingroup identifiers. The results are presented and discussed.

Description: ICT integration in secondary schools in Sub-Saharan Africa is still at an early stage and already faces several setbacks that may undermine the various initiatives undertaken by governments and the private sector to promote the use of computers in schools. Based on literature and other research, this may be attributed to the fact that no guidelines for proper ICT adoption in secondary schools exist; and furthermore, most integration cases were done haphazardly with no systematic approach based on the existing frameworks or tailored towards the real context in the schools concerned. The present study aimed to provide guidelines for the successful integration of ICT into schools in Cameroon. A review of some existing frameworks for ICT integrations in schools, as well as the innovative pathways that some developing countries have taken to ensure the successful integration of ICT into schools were explored through a literature review, revealing the trends and challenges of ICT integration in schools in Sub-Saharan Africa. The current status of ICT in schools in Cameroon being at an introductory stage was established from the available literature. This led to the use of a single case study from the Western Region of Cameroon, where four secondary schools were selected from the most advanced schools in terms of ICT integration. Participants consisting of principals, ICT co-ordinators, teachers, and students were interviewed, in order to establish the current status of ICT in each school, as well as those factors affecting or promoting the adoption of ICT. Teachers’ and students’ surveys, as well as existing documentation were used to triangulate the data gathered from interviews with school principals and ICT co-ordinators. Data were descriptively analysed – and the findings revealed that ICT is at the introductory stage of integration in the Fluck’s Model of ICT development in schools. At school level, the lack of infrastructure and an ICT adoption plan were found to be the key opposing factors to ICT integration, whereas several enablers were identified, such as the positive attitude of teachers towards ICT, the existence of a minimum recurring budget for ICT adoption through parents’ funding, as well as the continually decreasing cost of ICT infrastructure in the market. Based on the findings and experiences from successfully proven projects, a set of guidelines were derived for schools’ decision-makers. It is critical to put in place a well-structured policy for ICT in the school and to recognise all the ICT-related costs.

Description: State control of marketing agricultural or forestry products may lead to a trade monopoly and restricted competition, resulting in inequitable returns to producers. Consequently, market deregulation for agriculture and other natural products has been advocated to improve market efficiencies, participation and returns for the producers and local traders. The study examines the impact of deregulation of state marketing controls on collection, sale and returns to extractors and traders from non-timber forest products. It assessed whether deregulation policy resulted in greater benefits to primary extractors and a win–win situation for both producers and traders? Mixed effects were found, with no significant changes in terms of trade, demand, or quantum of consumption; but there was an overall increase in the procurement price for several products following deregulation. The collection and farm gate price of tree based oilseeds and honey increased due to lower transaction costs, and ease of trading with a continued demand for these products. The impact on less valuable products was insignificant. Abolition of monopolistic trading increased competition and had a pull effect on the local market prices of several NTFPs. Although traders paid a higher price to procure products, overall they also benefited being able to sell the purchased products to merchants and manufacturers at a better margin than previously.

Description: The fragmented nature of modern health care provision makes it increasingly difficult to achieve continuity of care. This is equally true in the context of the South African healthcare landscape. This results in a strong emphasis on the informational dimension of continuity of care which highlights the importance of the continuity of medical records. Paper-based methods of record keeping are inadequate to support informational continuity of care which leads to an increased interest in electronic methods of record keeping through the adoption of various Health Information Technologies (HITs). This research project investigates the role that various HITs such as Personal Health Records (PHRs), Electronic Medical Records (EMRs), and Health Information Exchanges (HIEs) can play in improving informational continuity of care resulting in the development of a standards-based technological model for the South African healthcare sector. This technological model employs appropriate HITs to address the problem of informational continuity of care in the South African healthcare landscape The benefits that are possible through the adoption of the proposed technological model can only be realized if the proposed HITs are used in a meaningful manner once adopted and implemented. The Delphi method is employed to identify factors that need to be addressed to encourage the adoption and meaningful use of such HITs in the South African healthcare landscape. Lastly, guidelines are formulated to encourage the adoption and meaningful use of HITs in the South African healthcare landscape to improve the continuity of care. The guidelines address both the technological requirements on a high level, as well as the factors that need to be addressed to encourage the adoption and meaningful use of the technological components suggested. These guidelines will play a significant role in raising awareness of the factors that need to be addressed to create an environment conducive to the adoption and meaningful use of appropriate HITs in order to improve the continuity of care in the South African healthcare landscape.

Description: This conceptual paper is based on experiences and insights which have emerged from my quest to develop a conceptual framework for working with the term ‘heritage’ within an education for sustainable development study that I am currently conducting. Of specific interest to me, and having potential to improve the relevance and quality of heritage education in southern Africa, given the region’s inherent cultural diversity and colonial history, is the need for ‘heritage construct inclusivity’ within the processes constituting heritage education practices. Working around this broad research goal, I therefore needed to be clear about what I mean or refer to as heritage. I realised, however, how elusive and conceptually problematic the term ‘heritage’ is. I therefore, drawing from literature and experiences gained during field observations and focus group interviews, came up with the idea of working with three viewpoints of heritage. Drawing on real life cases I argue that current heritage management and education practices’ failure to recognise and respect the evolving, interconnectedness and multi layered nature of heritage, partly explain the same practices’ lack of relevance and agency to enhance the sustainable management of local heritage resources. I also suggest a few ideas which heritage educators in the context of post-colonial southern Africa may need to consider in their everyday heritage education practices. I also introduce the notion of conceptualising heritage as ‘cultural landscapes’, within which the evolving, dissonant and interconnected nature of heritage, and associated heritage constructs, may be reconciled.
