  • Description: This research engages with a contemporary theoretical debate in the literary field, namely the ability of fictional texts to contribute to archival records. Contemporary research in archival discourse suggests that there are many intersections between fiction and the archive. Using Hamilton and others’ seminal text Refiguring the Archive (2002) and Pasco’s “Literature as Historical Archive” (2004) as point of departure, this dissertation offers an analysis of the South African English translation of Marlene van Niekerk’s Agaat (2004, translated 2006). In both form and function, the novel is viewed as a simulation of an archive. In Agaat, Van Niekerk has compiled a fictional archive of two indigenous South African cultures through her portrayal of the two main characters: Afrikaner culture during apartheid as embedded in the focalization of Milla de Wet and remnants of Khoi and/or San culture as emerge from the fictionalised subjectivity of her coloured housekeeper-nurse, Agaat. Through a conceptual and theoretical exploration of archival discourse, I argue that literary texts, such as Van Niekerk’s novel, have the potential to refigure (or creatively redefine) the archive and to enhance its scope and relevance, especially as South Africa undergoes transformation.

  • Description: In this study, it was attempted to gain insight on coordination of decentralized health and social development services. Further, it was attempted to evaluate the coordinating arrangements of and relationship between decentralized provincial health and social development services with similar services rendered by district and local municipalities. Since the literature on coordination of decentralized services is limited, it is anticipated that this study will provide valuable information for further research on the topic. In the literature study undertaken however, it was evident that coordination of services increases the rate of effectiveness and efficiency in the delivery of public services. It was found that role players can no longer afford to work in different compartments. They need to work cooperatively together in achieving unity of purpose, unity of effort as well as unity of action towards the realization of the objectives of government, that of rendering of public services. Thirty four respondents composed of mayors in Amathole District Municipality and Buffalo City Local Municipality, municipal managers for the respective municipalities, portfolio heads for health and social development services in the respective municipalities as well as two councillors, one in each municipality, were given questionnaires to complete. Also given questionnaires to complete were the political office bearers of the Provincial Department of Health and the Provincial Department of Social Development as well as respective Heads of the two departments. Again, officials of the five decentralized offices of the Provincial Department of Health and the Department of Social Development namely, Mbashe, Mnquma, Buffalo City, (v) Amahlathi and Nkonkobe, were given questionnaires to complete. The intentions of the study were to determine the effectiveness in coordinating the rendering of health and social development services between the Provincial Authority, the district as well as local municipalities in the Eastern Cape. Also, the intention was to determine the problem areas in the coordination of the health and social development services rendered by the above authorities. Lastly, the intention was to ascertain whether or not proper measures and standards are put in place for the effective coordination of health and social development services rendered by the above authorities. The findings of the study confirmed firstly, that there is a need to coordinate decentralised health and social development services with similar services rendered by district and local municipalities as well as other role players. Secondly, the study confirmed that departments and municipalities experience problems of coordinating decentralised health and social development services. Thirdly, the study confirmed that there are measures in place to coordinate decentralised health and social development services with similar services rendered by municipalities and other role players. Lastly, the study confirmed, that such measures are not properly defined and need to be strengthened.

  • Description: This study is about Continuous Assessment (CA) in teaching and learning, a new concept and approach in independent Namibia. The country's education system was reformed shortly after independence in 1990 to fulfill the intention for Education for All. The Namibian education system then moved from a behaviorist to constructivist philosophy of education. The move made from one philosophy to another resulted in many changes in teaching and learning including changes in assessment in education. CA is born out of a constructivist philosophy. It is believed to facilitate learning with understanding. In this study I explored the understanding of Oshikwanyama teachers and their practice of CA in teaching and learning. Interviews, classroom observations and document analysis were used. The research focused on 10 participants in the Ohangwena and Oshana regions. The participants ranged from a Head of Department to members of the curriculum panel, subject advisors and Oshikwanyama subject facilitators as well as teachers at the classroom level. It was revealed that generally speaking, CA as a term is understood, but the practice is not well implemented. In the practice of CA, instead of learners being assessed for further learning, the emphasis is on scored marks without further assistance in learning. Further, the collection of marks during CA is often seen as largely for the purpose of contributing to the marks for summative final marks. Informal assessment which is part of CA was not given attention, which is a key factor preventing the effective use of CA in teaching and learning. Methods such as marking grids that are provided in the syllabus, as well as portfolios and learners' profiles, were not mentioned in the interviews nor observed as being in use. Participants in the study did acknowledge that they did not fully understand how best to implement CA. Overall, the evidence pointed to a conclusion that the identified shortcomings in the implementation of formative assessment is limiting the realization of the rich potential for CA as a day-to-day tool to facilitate learning for understanding in the observed classes.

  • Description: Design guidelines are used in interaction design (IxD) for physical design and for evaluating the usability of designs and interactive products. Guidelines are widely used for physical design and evaluation, but have a number of problems. IxD patterns have been proposed as an alternative to guidelines, as they are claimed to have several advantages over guidelines. A small number of empirical studies provide evidence that patterns are beneficial when used in IxD. Additional research on the usefulness of IxD patterns is required. The primary research question investigated in this thesis was thus: How useful are IxD patterns as physical design and evaluation aids in IxD, as compared to design guidelines? The role of guidelines and patterns as design and evaluation aids in IxD was investigated and a comparison of guidelines and patterns, based on a set of guideline and pattern properties, was conducted. The concept of pattern and guideline usefulness was explored and a research agenda for guidelines and patterns was identified, together with a set of research questions for an empirical study. The empirical study of the use of patterns for evaluation, redesign and new design, as compared to guidelines, was conducted at the Nelson Mandela Metropolitan University in 2004. The participants were a purposive sample of post-graduate Computing students, who were regarded as novice interaction designers. Two equivalent groups were formed, one that used patterns and one that used guidelines. Patterns were found to be as useful as guidelines when used as evaluation aids. Guidelines and patterns were identified as effective tools for identifying and explaining usability issues and design features. Best-effort matched sets of guidelines and patterns produced substantially different result sets when used to identify issues and features, with fairly low overlap. A substantial evaluator effect was observed for the use of guidelines and patterns for evaluation, and the results obtained were similar to those obtained by Molich et al. in their Comparative Usability Evaluation (CUE) studies. There was no statistically significant difference between the effectiveness of guidelines and patterns for evaluation. There was also no statistically significant difference between the perceived efficiency, effectiveness and satisfaction in use of guidelines and patterns for evaluation. Guidelines and patterns were found to be used in similar ways for evaluation. Patterns were found to be more effective than guidelines for redesign. Patterns were found to be as useful as guidelines when used for new design. There was no statistically significant difference between the effectiveness of guidelines and patterns for new design. There was also no statistically significant difference between the perceived efficiency, effectiveness and satisfaction in use of guidelines and patterns for redesign and new design. Guidelines and patterns were found to be used in similar ways for design. There was no statistically significant difference between the perceived usefulness of the format, content, ease of learning, and usefulness as personal and shared design languages, of guidelines and patterns. Both participant groups were equally agreeable to using guidelines and patterns in the future. The perceived usefulness of pattern collections was found to depend on the usability of the collection interface and the content quality of the patterns. The results of the empirical study thus provided empirical evidence that patterns were as useful as guidelines for evaluation and new design, and were perceived as positively as guidelines were. Patterns were found to be superior to guidelines for redesign. Patterns can therefore be used with a measure of confidence as early stage design aids for physical design and evaluation in the future. In addition to these findings, a number of opportunities for further research were identified.

  • Description: Manganese acetate octakis-(2-diethyaminoethanethiol) phthalocyanine (AcMnODEAETPc) was newly synthesized and characterized by spectroscopic and electrochemical methods. Solution electrochemistry of the complex showed three redox processes assigned to MnIIIPc−1/MnIIIPc−2, MnIIIPc−2/MnIIPc−2 and MnIIPc−2/MnIIPc−3 species. The new molecule was polymerized onto a glassy carbon electrode (GCE) to form thin films of different thickness, giving poly-10-AcMnODEAETPc-GCE, poly-20-AcMnODEAETPc-GCE and poly-30-AcMnODEAETPc-GCE, where 10, 20 and 30 represent the number of voltammetry scans during polymerization. Three distinct redox processes were observed on the modified electrode in 0.1 M phosphate buffer solution, pH 5, which confirmed the formation of the polymer. The current signal due to the herbicide, bentazon, was dependent on film thickness; the best signal was obtained on poly-20-AcMnODEAETPc-GCE while poly-10-AcMnODEAETPc-GCE gave the least signal. However, the signals due to the herbicide were better on the different films compared to the bare electrode. Electrochemical impedance spectroscopy (EIS) technique revealed that differences in film thickness offered different charge transfer resistances, Rct, hence difference in current signals for bentazon oxidation were observed on these films. A Tafel slope of 77 mV/decade, obtained for the herbicide on poly-20-AcMnODEAETPc-GCE, denotes a fast one electron transfer followed by a slow chemical step in the electro-oxidation of bentazon. The voltammetry signals of the herbicide on the films indicated the likely involvement of ring-based redox processes in the detection of the herbicide. A plot of background corrected current response, on this film, versus the concentration of bentazon was linear within the range 50–750 μM with a detection limit of 2.48 × 10−7 M.

  • Description: With the move towards global and multi-national companies, information technology infrastructure requirements are increasing. As the size of these computer networks increases, it becomes more and more difficult to monitor, control, and secure them. Networks consist of a number of diverse devices, sensors, and gateways which are often spread over large geographical areas. Each of these devices produce log files which need to be analysed and monitored to provide network security and satisfy regulations. Data compression programs such as gzip and bzip2 are commonly used to reduce the quantity of data for archival purposes after the log files have been rotated. However, there are many other compression programs which exist - each with their own advantages and disadvantages. These programs each use a different amount of memory and take different compression and decompression times to achieve different compression ratios. System log files also contain redundancy which is not necessarily exploited by standard compression programs. Log messages usually use a similar format with a defined syntax. In the log files, all the ASCII characters are not used and the messages contain certain "phrases" which often repeated. This thesis investigates the use of compression as a means of data reduction and how the use of semantic knowledge can improve data compression (also applying results to different scenarios that can occur in a distributed computing environment). It presents the results of a series of tests performed on different log files. It also examines the semantic knowledge which exists in maillog files and how it can be exploited to improve the compression results. The results from a series of text preprocessors which exploit this knowledge are presented and evaluated. These preprocessors include: one which replaces the timestamps and IP addresses with their binary equivalents and one which replaces words from a dictionary with unused ASCII characters. In this thesis, data compression is shown to be an effective method of data reduction producing up to 98 percent reduction in filesize on a corpus of log files. The use of preprocessors which exploit semantic knowledge results in up to 56 percent improvement in overall compression time and up to 32 percent reduction in compressed size. , TeX , pdfTeX-1.40.3

  • Description: The aim of this study was to investigate the alignment of human resources with the strategic plan at Emalahleni Local Municipality in Chris Hani District Municipality, Eastern Cape. The alignment of the human resources plan with the strategic plan is the requirement for inclusive integrated planning legislated in local government acts. The research in this area does not investigate the alignment of the human resources plan with the strategic plan especially in Eastern Cape local government. Integrated planning which is inclusive of human resource development and performance management is a legal requirement legislated in the Local Government Municipal Systems Act no. 32 of 2000. From the literature review it was evident that it is essential for organisations to have a clear vision and measurable specific attainable time-bound objectives which could transpire into measurable performance standards. For achievement of the strategic objectives human resource planning of the organisation has to be informed by the objectives of the organisation so that there can be a relationship between the employees and the business in which they are employed. The literature raised the importance of the involvement of the human resource manager and employees in general in the development of human resource strategy and strategy planning in the organisation and the performance of the organisation. A combination of the qualitative and quantitative approaches was used to achieve the objectives of evaluation research used as the research design in the study. A document study, interviews, and questionnaires were used to investigate the alignment studied. The participants were employees ranging from managers to lowest-level employees. The main patterns that emerged from collected data were the lack of clear strategic objectives, lack of alignment of the strategic plan and human resources, the lack of human resource strategy and development, and performance management systems. Emalahleni Local Municipality was then advised to review and reconceptualise its strategy plan to contain objectives which were clear, specific and measurable, and strategic objectives to include a human resource strategy for human resource alignment with the strategic plan. Such alignment could lead to integrated planning which could be measured to evaluate failure or success in the achievement of the strategic objectives.

  • Description: Towards the end of one’s career, there’s a powerful inclination to look backwards instead of forwards. You become more interested in histories, biographies and obituaries; you reflect on your own life and career. It’s not inevitable, and it can be resisted. Marshall McLuhan was well into his 50s – an obscure Canadian Eng Lit academic – when he had his vision of the nature and future of the media and anticipated a ‘global village’ that the Internet has turned into a reality since his death in 1980 (McLuhan and Powers 1989) – but more on that in due course. Cui Bono? At first I gave into the tendency to look back. Initially, for this lecture, I thought to analyse my own career in South Africa in terms of who benefited most from it: South African anthropology and my students … or me. I would call the lecture ‘Cui Bono?’ But then I realised, with Latin tags on the way out, younger colleagues and students in the audience might think I was referring to a traditional Australian greeting (Coo-ee) and an Irish philanthropist pop singer (Bono). The title would be totally mystifying to many until I explained that it meant ‘to whom the good’ – in other words, who benefits? But there were other objections to this project besides the title. Even the most postmodern of reflexive anthropologists would balk at making such a self-assessment – it was not for me to judge. Anyway, I already knew the answer: My career in South Africa has not been impeded by political harassments, imprisonment or conscription. I did make some small negligible contributions to the ‘struggle’ through writing or drawing, and I did some community service, on campus or off in the same way. At a critical stage I assisted with the process that eventually produced a national staff association, now called NTESU. The only price I have paid for these distractions from serious publishing at a critical stage of my career was deservedly slow promotion. I continue to contribute to the community mainly through membership of the older of Grahamstown’s two very active Rotary clubs. It’s all I have time for, but nothing to boast about. In sum, I’ve enjoyed what my long-term colleague and Grahamstown’s Citizen of the Year (another Rotary initiative) Michael Whisson likes to call ‘sheltered employment’ – his typically ironic way of reminding us of how privileged we academics are, doing what we enjoy, in pleasant surroundings, among intelligent colleagues and the cream of our youth, with plenty of flexi-time and opportunities for subsidized travel. And now I have benefited again by being promoted to full professor without sufficiently earning my keep through subsidies on academic outputs. Whatever I might have given back through teaching and administration the net is in my favour, and I am grateful beyond words.

  • Description: In this study a method was developed to identify and quantify platinum(II) complexes of the type [PtCl4-n(OH)n]2- and [PtCl4-n(H2O)n]2-n. Separation of the various species was achieved with the aid of a hyphenated reversed phase HPLC-ICP-MS technique coupled with an ion-pairing reagent, HMHDCl2. The adsorption of HMHD2+ onto a C-18 column was investigated by generating a series of breakthrough curves. It was found that the selectivity for high charge density anions originates from its low surface coverage relative to TBA+, which on the other hand could not separate Pt(II) complexes. The peaks in the chromatographic traces were assigned by following the stepwise ligand substitution of [PtCl4]2- in hydroxide medium with UV/Vis spectrophotometry and HPLC-ICP-MS simultaneously. A computer program was written by the author to analyse chromatographic data by deconvoluting the chromatogram into its individual components and calculating the mole fraction of each component. The validity of the consecutive pseudo-first order model was validated by constructing 3D Mauser diagrams with the raw spectrophotometric data (A1 vs A2 vs A3). Additional software was used to simulate the raw spectrophotometric data and processed chromatographic data. The pseudo-first order rate constants obtained in both cases were in agreement with each other. Hence, peaks were assigned to [PtCl4]2-, [PtCl3(OH)]2-, [PtCl2(OH)2]2-, [PtCl3(H2O)]-. The molar extinction coefficient spectra of [PtCl3(OH)]2- and [PtCl2(OH)2]2- were obtained by simulating the spectrophotometric data at wavelengths from 280 to 450 nm. The reaction of [PtCl4]2- with sodium hydroxide was investigated with UV/Vis spectrophotometry at 25 °C. A rate constant consisting of a first and second order term was obtained. The first order term agreed with what has been reported in the literature for aquation of [PtCl4]2- at 25 degrees C. The influence of temperature was established by conducting the experiment at different temperatures. It was found that the reaction proceeds essentially via aquation at elevated temperatures.

  • Description: There is a well-acknowledged communication or knowledge gap between scientists and decision-makers. Many scientists who take on the challenge of narrowing this gap operate on the understanding that their role is to communicate their findings in a one-way flow of information: from science to decision-makers. However, to be effective scientists must engage in an ongoing social learning process with decision-makers, and regard themselves as facilitators, and also as one among many stakeholders who have valid and important ecological knowledge. The developing world poses some particular challenges in this regard, specifically in terms of the large number of local level subsistence resources users who are important de facto decision-makers. We examine four natural resource management case studies from South Africa that differ in spatial scale and complexity, ranging from a single village to a whole biome. We distil seven lessons to help guide development of social learning processes and organizations in similar situations relating to natural resource planning and management. The lessons pertain to: maintaining ‘key individuals’ within social learning processes; the role of researchers; the formulation of research questions that social learning processes require adaptive long-term funding and capacity support; that local resource users are key decision-makers in developing countries; some perspectives on knowledge; and the need to measure research success.

  • Description: This paper reports on a collaborative action research case study into Grade 10 teaching and learning of visual literacy in a rural high school into the Eastern Cape, South Africa. Visual literacy is a new aspect that has been incorporated in English First Additional Language National Curriculum Statement (Grade 10-12), which has been implemented in Grade 10 from 2006. With the aim of gaining knowledge and improving performance in visual literacy, I designed a unit of lessons, which exposed learners to visual grammar and visual texts and I collected data around the implementation of the lesson unit as evidenced by journal writing, interviews and non-participant observation. The data revealed that visual literacy could be taught meaningfully in a rural high school as the learners could identify, cut, paste and critically discuss elements of visual language and they finally designed their own advertisements in groups. However, the following factors emerged as hindrances to the successful teaching of visual literacy in this case: lack of resources; learners' lack of a foundation in visual literacy from Grades 7-9; and problems revolving around time management and pacing.

  • Description: This thesis is a critical examination of the origins, barriers and prospects for a working class-led civil society as it sought to democratise Zimbabwe’s post-colonial state. It is an interdisciplinary but historically informed analysis of how advanced capitalist development promoted the emergence of social movement unionism with a potentiality to advance democracy in Zimbabwe. Despite occurring on a much smaller and thinner scale, the evolution of civil society in colonial Zimbabwe was akin to what happened in 19th century Britain where capitalist expansion presented a foundation for democratisation. However, big underlying barriers exist in Zimbabwe, resulting from various forms of authoritarian structures and forcible mobilisation strategies emanating from colonialism and the protracted war of liberation. ZANU PF’s violent reaction to memory contests by non-participants in the war of liberation seeking an alternative political agenda attest to the controversial and polemical nature of struggles over memory and forgetting in contemporary Zimbabwean politics. These structural impediments forestalled the organic growth of civil society in Zimbabwe, thereby explaining its inchoate status and the failure to significantly determine the course of public policy. While recognising the democratic aspirations and capacities of the working class in precipitating political change, this thesis takes into consideration the impact of other factors on state-society relations. These include deepening state barbarism, globalisation, and technological advances in communication, transnational civil society, a dysfunctional economy, migration and remittances. Finally this thesis presents an optimistic scenario about the prospects for civil society and democratisation in Zimbabwe. I argue that the revival of the productive sectors of the economy can possibly strengthen the labour movement and revive its capacities for ushering in a democracy.

  • Description: This paper reports on the use of thiol derivatised cobalt phthalocyanines as self assembled monolayers (SAMs) on gold disk electrode, gold ultramicro-cylinder electrode (UMCE) and on gold coated fiber for the detection of L-cysteine. The complexes are peripherally and non-peripherally substituted with phenylthio substituents. The SAM modified electrodes showed enhancement of catalytic currents and overpotential reduction occurred on the gold modified electrodes with different geometries. Electrocatalytic oxidation of L-cysteine on SAM modified gold coated fiber was reported for the first time. The gold coated fiber and ultramicro cylinder electrode were less stable towards the electrocatalytic oxidation of cysteine compared to its oxidation on the gold disk. The gold disk electrode gave better catalytic performance in terms of stability and reduction of overpotential.

  • Description: Even though many organizations invest in IT, the value that IT is expected to contribute is still not clearly understood. Researchers agree that IT has become a crucial element to business operations and business existence. However, while there is continued investment in new information technologies and systems, organizations are not certain whether significant value is derived from IT investments. The failure to realize good return on IT investments is ascribed to a lack of understanding of IT by organizations and also the failure by organizations to align IT strategies with business strategies. The lack of alignment leads to the failure to match the right IT to the correct task, which leads to the poor application of systems and poor allocation of human resources to tasks. Therefore, organizations such as Small and Medium Enterprises (SMEs) in particular Boutique Hotels, are noted for their failure to derive better IT value. Their unique characteristics are understood to be influential in the way IT is used and managed by affecting the delivery of value from technology. In order to enable Boutique Hotels to derive more value from IT, the IT governance frameworks, Val IT and CobiT (ITGI, 2007), were examined as these integrate good practices to ensure that an organization‘s IT supports the business objectives. In addition, the Task Technology Fit (TTF) (Goodhue and Thompson, 1995) and Gap Analysis (Heeks, 2001) theories were highlighted as these prescribe the platform ideal for more value to be derived from IT. The current status of Boutique Hotels in Buffalo City was assessed through the use of questionnaires and interviews. The collected data was analyzed and resulted in the development of a model that can be used by Boutique Hotels in order to derive more value from IT and to maximize the use of IT.

  • Description: The syntheses and characterization of 2,3-octakis-(3-pyridyloxyphthalocyaninato) indium(III) and quaternized 2,3-octakis-(3-pyridyloxyphthalocyaninato) indium(III) are described. The ground state electronic absorption spectra, photophysics and photochemistry of both dyes in DMSO as well as that of the quaternized compound in aqueous solution are also presented. A comparison of the photophysical and photochemical parameters of the two dyes revealed that quaternized 2,3-octakis-(3-pyridyloxyphthalocyaninato) indium(III) was a better photosensitizer than its unquaternized counterpart. The quantum yield values of fluorescence (ΦF), triplet state formation (ΦT) and singlet oxygen formation (ΦΔ) for the cationic dye were found to be 0.03, 0.68 and 0.66 respectively in DMSO; these values were higher than those for 2,3-octakis-(3-pyridyloxyphthalocyaninato) indium(III), which exhibited values of 0.02, 0.66 and 0.63, respectively in DMSO. The values for the cationic dye in aq. solution were 0.02, 0.59 and 0.56 respectively, suggesting that the water-soluble quaternized 2,3-octakis-(3-pyridyloxyphthalocyaninato) indium(III) offers potential as a photosensitizer in photodynamic therapy treatment.

  • Description: Music libraries are relatively recent additions to South African library collections and attempts at forming a music library association have been thwarted through a number of financial and historical societal limitations. Consequently, many South African music librarians feel isolated from the field. This paper examines the effects of this isolation and the benefits that closer association for the librarian could bring. Future outlooks for music libraries in South Africa are discussed and suggestions made for a more positive future. Les bibliothèques de musique sont des additions relativement récentes aux collections des bibliothèques en Afrique du sud. Les tentatives de création d'une aßociation de bibliothécaires de musique ont été contrariées pour des raisons financières, historiques et sociales. Par conséquent, beaucoup de bibliothécaires de musique se sentent isolés du milieu. Cet article examine les effets de cette isolation et les bénéfices que pourrait apporter une aßociation qui rapproche les bibliothécaires. Il aborde des discußions sur des perspectives futures et émet des suggestion afin d'appréhender un avenir plus positif. Musikbibliotheken sind eine relativ neue Erscheinung im Bibliothekswesen Südafrikas. Die Gründung einer musikbibliothekarischen Vereinigung ist aus finanziellen und anderen Gründen heraus immer wieder gescheitert. Daher fühlen sich viele südafrikanische Musikbibliothekare beruflich isoliert. Der Artikel untersucht die Auswirkungen dieser Isolation und die Vorteile, die ein engerer Zusammenschluß den Bibliothekaren bringen könnte. Er wagt einen Ausblick in und macht Vorschläge für die Zukunft südafrikanischer Musikbibliotheken.
