  • Description: The Palaeoproterozoic Earth experienced a global glacial event at 2400 Ma that occurred during the transitional period from anoxic to aerobic conditions in the atmosphere and oceans. The Transvaal Supergroup in the Griqualand West Basin, South Africa, hosts glacial deposits and associated major iron and manganese deposits that are apparently related to these global changes. The focus of this study is to assess the stratigraphy and geochemistry of the glaciogenic Makganyene Formation, in order to constrain its palaeoenvironmental settings. The Makganyene Formation forms the base of the Postmasburg Group and has been regarded as resting on an erosive regional unconformity throughout the Northern Cape Province. Systematic regional field observations and regional mapping carried out during this study demonstrate that this stratigraphic relationship is not universal. The Makganyene Formation is, in fact, conformable with underlying formations of the Koegas Subgroup in the deep southern Prieska basin and rests on an unconformity only on the shallow Ghaap platform to the north-east. The Makganyene Formation displays lateral facies changes that reflect the palaeogeography of the study area, and the advance and retreat of ice sheets/shelves. Geochemical investigations of glacial strata of the Makganyene Formation demonstrate that underlying banded iron formations of the Transvaal Supergroup acted as the main clastic source for the diamictite detritus. Geographic variations in bulk composition of the diamictites correlate well with field observations, and show that sorting processes were controlled largely by the morphology of the palaeobasin. Carbon isotope results emphasize the transitional nature of the Makganyene Formation in terms of the environmental conditions that resulted in widespread global glaciation in the Palaeoproterozoic. On the basis of the above geological evidence, it is proposed that the Transvaal Supergroup in the Northern Cape Province represents a continuous depositional event that lasted approximately 250 Ma and hence provides a unique opportunity for assessing the transitional changes experienced by the Palaeoproterozoic Earth.

  • Description: The ichthyofaunal community structure, population dynamics and movement patterns in the small temporarily open/closed (TOCE) Grant’s Valley estuary, situated along the Eastern Cape coastline, were investigated over the period May 2004 to April 2005. Community structure in the littoral zone was assessed, while growth of selected ichthyofaunal species was investigated using the MULTIFAN model. Population size was assessed using mark recapture models and movement within the estuary using the Hilborn (1990) model. Total ichthyofaunal densities and biomass within the littoral zone ranged between 0.31 to 21.45 fish m⁻² and 0.20 to 4.67 g wwt m⁻², with the highest values typically recorded during the summer. Results of the study indicated that the ichthyofaunal community structure within the estuary was closely linked to the mouth phase and the establishment of a link to the marine environment via overtopping events. In the absence of any link to the sea, the ichthyofaunal community was numerically dominated by estuarine resident species, mainly Gilchristella aestuaria and to a lesser extent, by the river goby, Glossogobius callidus which collectively comprised ca. 88% of all fish sampled. The establishment of the link to the marine environment contributed to an increased contribution of marine breeding species (e.g. Rhabdosargus holubi, Myxus capensis and Atherina breviceps) to the total ichthyofaunal abundances. In contrast, total ichthyofaunal biomass was almost always dominated by marine breeding species by virtue of their larger sizes. Results of hierarchical cluster analyses did not identify any spatial patterns in the ichthyofaunal community within the littoral zone. Results of MULTIFAN analysis indicated estuarine resident fish species bred over an extended period with peaks occurring in the summer months. Conversely, marine breeding fish were shown to recruit into the estuary following overtopping and breaching events. Results of the mark-recapture experiment indicated a population of ca. 12 000 (11 219 – 13 311) individuals greater than 50mm SL. Marine-breeding species (R. holubi, Monodactylus falciformis, and two mullet species) numerically dominated the ichthyofauna, possibly as a result of their effective use of overtopping events. The two mullet species, M. capensis and Liza richardsonii, and the Cape stumpnose, R. holubi moved extensively throughout the estuary, while the remaining species exhibited restricted movement patterns possibly due to the preference for refuge and foraging areas associated with reed beds. The observed movement patterns of individual fish species appeared to be associated with both foraging behaviour and habitat selection.

  • Description: The identification of mammals through the use of their hair is important in the fields of forensics and ecology. The application of computer pattern recognition techniques to this process provides a means of reducing the subjectivity found in the process, as manual techniques rely on the interpretation of a human expert rather than quantitative measures. The first application of image pattern recognition techniques to the classification of African mammalian species using hair patterns is presented. This application uses a 2D Gabor filter-bank and motivates the use of moments to classify hair scale patterns. Application of a 2D Gabor filter-bank to hair scale processing provides results of 52% accuracy when using a filter-bank of size four and 72% accuracy when using a filter-bank of size eight. These initial results indicate that 2D Gabor filters produce information that may be successfully used to classify hair according to images of its patterns.

  • Description: The aim of all companies is continuously to improve their products and/or services. Managers need to understand what service quality entails and what measures to take to ensure that quality is upheld and employees are satisfied. Cost-saving initiatives often require certain changes to take place within the organisation. In the event of such changes, the psychological contract is often violated, which may have a positive or negative effect on the affected individuals. Management expects to get more work done with fewer employees, who in turn are expected to keep up the service quality. The current shortage of medical technologists in the country has made it impossible for them to cope with the heavy workload. As a result, many leave the profession and venture into something completely different. Those that are left become completely demotivated; they experience less job satisfaction and show less commitment to their work. However, some may even embrace the changes because to them it may mean bigger and better challenges. The aim of this study is to identify which approaches management took to ensure cost saving and how these approaches impacted on the behaviour of employees. A literature review was conducted to determine what the theory reveals about cost saving and its impact on employee behaviour. This was followed by an empirical survey conducted within the National Health Laboratory Services in the Ibhayi region. Finally, the practical findings and literary theory were compared to make recommendations to management on how to ensure positive employee behaviour and boost employee morale.

  • Description: Introduction and Relevant Details: This research investigates the impact of inbound logistics' activities on the operational performance of the business within the branches of the South African Post Office (SAPO) in the Eastern Cape Province. The study basically hypothesises a statistically significant positive correlation between inbound logistics' activities and the operational performance of the business with regards to revenue generation and operational costs in particular. A sample of 100 branch offices was randomly selected. A 50-item questionnaire was administered by mail to the branches to collect the data during September 2005, and statistical tests for correlation were conducted on at least five dependent variables; stock procurement costs, effects on revenue, number of stock variation occurrences, order variation occurrences and the stock holding effects. Results of Data Analysis: The results of 88 respondents (88%) showed the existence of the significant positive relationship between the inbound logistics activities and the operational performance of the business at the South African Post Office branches as proposed by the study. The Spearman Rank Correlation tests were above 0.7 for most of the tested variables, showing a strong relationship. The inbound logistics' activities were also found to be positively correlated to revenue generation as well as to the operational expenses of the business. Conclusion and Recommendations: The findings allowed the researcher to conclude also that whatever improvements are made to the inbound logistics will also impact on the operational performance of the business, while failures in the inbound logistics will do so negatively. Business endeavours to maximise revenue and minimise costs are directly affected by the inbound logistics' activities. The branches of the SAPO seemed to be dissatisfied with most of the services rendered by the Supply Distribution Centre (SOC) of the SAPO, and such services have negatively affected the achievement of revenue targets at the branches as well as the operational costs. Holistic approaches to developing positive perceptions in the branches together with improving service activities at the SOC are recommended. Collaborative initiatives between branches and the SOC, reviewing the lead-times and the establishment of proper structures to handle supply chain queries, enhanced by information system technology to provide accurate and up-to-date information to branches and related parties about stock order issues are required . Areas of further research highlighted include the inbound logistics' activities of the SOC and the effectiveness of company policies as a guide to Supply Chain Management (SCM).

  • Description: Cultural and educational functions of public service broadcasting come at a fortuitous time, as the changing environment of broadcasting is on various agendas. At the heart of this is the question of the present and future status of public service broadcasting. Major changes have taken place in the political economy of the media and the world economy at large, technological advancement has resulted in privatization and commercialization of the media. In most societies where these changes have taken place, public service broadcasting has been threatened by the rapid rise of commercial institutions, resulting in stiff competition for audiences. This study will examine the extent to which the adoption of the Commercialization Act (No 26) of 2001 in Zimbabwe has affected Radio Zimbabwe’s role as a public broadcaster. The study is based on the hypothesis that with the adoption of the Commercialization Act, Radio Zimbabwe is no longer playing its public service role effectively. The current nature of programming at Radio Zimbabwe as the research hopes to show will highlight tremendous changes towards a commercial logic. The study uses a combination of document analysis, secondary literature and qualitative interviews.

  • Description: The influence of the phytoplankton size composition in mediating the trophic interactions between the bacteria, phytoplankton, microheterotrophs (<200 μm) and mesozooplankton (>200 μm) was investigated on three occasions in a warm temperate, temporarily open/closed estuary situated along the southern African coastline. Results of the investigation indicated that the microheterotrophs represented the most important consumers of bacteria and chlorophyll (chl)-a <5.0 μm. The low impact of the mesozooplankton on the bacteria and chl-a <5.0 μm during the study appeared to be related to the inability of the larger zooplankton to feed efficiently on small particles. During those periods when total chl-a concentration was dominated by picophytoplankton (<2.0 μm) and microphytoplankton (>20 μm), mesozooplankton were unable to feed efficiently on the chl-a due to feeding constraints. In response to the unfavorable size structure of the phytoplankton assemblages, mesozooplankton appeared to consume the microheterotrophs. The negative impact of the mesozooplankton on the microheterotrophs resulted in a decrease in the impact of these organisms on the bacteria and the chl-a <5.0 μm. This result is consistent with the predator-prey cascades. On the other hand, when the total chl-a was dominated by nanophytoplankton (2–20 μm), mesozooplankton were able to feed directly on the phytoplankton. Results of the study indicate that size structure of the phytoplankton assemblages within estuaries plays an important role in mediating the trophic interactions between the various components of the plankton food web.

  • Description: Despite the extensive research undertaken in the subject area of services marketing, much is still unknown to service providers of specific services in terms of service delivery concepts. This study attempts to address this limitation. The study revolves around the customer relationship management and service quality of banks. Service firms, including banks, are vitally important to the economy of any country, as they contribute to its Gross Domestic Product (GDP) and employment rate. However, to survive in a complex, competitive business environment, service firms are required to focus on their clients’ needs. Specifically, banks can focus on their relationships with clients and levels of service quality. In order to establish the influence of selected variables on the customer relationship management (CRM) of banks and the influence of CRM on the service quality of banks, an empirical investigation was conducted. The aim of this study was to quantify significant relationships among selected variables; therefore the positivistic research paradigm was used. The sample consisted of banking clients in the Nelson Mandela Metropolitan area. The sample size was 290, with a response rate of 91.03%. The empirical investigation revealed that significant positive relationships exist between both the knowledgeability, and attitude, of bank employees and a bank’s CRM. These relationships imply that more extensive knowledgeability of bank employees and bank employees with more positive attitudes lead to improved, maintained relationships between a bank and its clients. In addition, the empirical investigation revealed that CRM positively influences the service quality of banks. This relationship implies that if a bank successfully maintains relationships with its clients, the bank’s level of perceived service quality would increase. Additionally, the empirical investigation has shown the relationship between a banking client’s age and the CRM of a bank. The higher the age of a banking client, the more that client considers the CRM of a bank to be important. There exists a relationship between a banking client’s education level and the perceived service quality of a bank. If a banking clients’ education level increases, the importance of their bank’s service quality decreases and, conversely, a banking client with a lower level of education regards the service quality level of a bank as more important than higher qualified clients. The study indicated that strategies to improve, specifically, the knowledgeability and attitude of bank employees can and should be implemented by banks in ways to positively influence their CRM and ultimately their service quality. In effect, this will increase client satisfaction and ensure client loyalty to the bank. Ultimately, this will contribute to the bank’s success, which will ensure economic stability and prosperity for a country.

  • Description: The Kariega Estuary channel was sampled using an otter trawl and the demersal fish catch analysed using the PRIMER statistical package. A biological-environmental (BIOENV) analysis was undertaken using the catch per unit effort ichthyofaunal data from the spring/summer period of 1996/97 and concurrent water temperature, salinity and turbidity data. No strong correlations between the ichthyofauna and recorded physico-chemical parameters were documented, although temperature did show a weak correlation to demersal fish distributions. A second sampling programme undertaken in 2004 was specifically designed to test the influence of sedimentary characteristics on the distribution patterns of the dominant demersal species.

  • Description: Various oxygen- and nitrogen-donor ligands were investigated as potential zirconium masking agents in zirconium tanning. α-Hydroxycarboxylic acid ligands were identified as effective zirconium(IV) chelators in acidic aqueous solution. Glycolic acid, lactic acid, mandelic acid, 4-hydroxymandelic acid, 4-chloromandelic acid and 4-bromomandelic acid complexes were synthesised, isolated and characterised using a range of analytical techniques. Linear Free Energy Relationships were examined to optimise the stability of the zirconium complexes. Hammett [sigma] plots and Yukawa-Tsuno modified σ plots of the mandelate ligand and zirconium complex series indicated that inductive effects dominate within the benzene ring, however, mesomeric effects are significant outside the ring. Zirconium 4-hydroxymandelate complex solutions were identified as the most effective tanning agents and achieved shrinkage temperatures of 80 and 97ºC for hide powder and goatskin, respectively. The zirconium and 4-hydroxymandelic acid interact synergistically to yield leather equivalent to combination tanned leather in one step. Tanning was performed similarly to vegetable tanning processes with a pickle pH of approximately 5 and fixation was achieved upon acidification. Pilot-scale tanning of goatskin produced white tanned leathers and crust leathers which were physically and aesthetically comparable to matched chromium tanned material.

  • Description: Human Immunodeficiency Virus (HIV) and Acquired Immuno-Deficiency Syndrome (AIDS) have brought about a global epidemic far more extensive than was predicted even a decade ago (van Rensburg, 2002:1). South Africa has one of the highest HIV prevalence rates in the world (South African Department of Health, 2000: 5), it still increase yearly. Before a vaccine and/or effective treatment become available, effective education and information campaigns are necessary for preventing the spreading of HIV and AIDS (WHO (the World Health Organization), 1988:21). According to WHO and ICN (International Council of Nurses) (1988:12), Nurses can play a pivotal role in the education of patients, their families and friends with regard to the prevention of HIV and AIDS transmission, so as to control the spread of this disease. In South Africa, more than 60 percent of the healthcare human resources comprise professional nursing practitioners (Muller, 2002: 95). Therefore, the education and training of nurses is one of the effective methods to preventing further spread of HIV and AIDS infection in South Africa. Accordingly, nurses need to reduce both personal and occupational risk of becoming infected with HIV themselves, as well as provide education to patients and their families. Before effective and efficient in-service education guidelines on the prevention of HIV and AIDS transmission can be developed, any knowledge deficit and negative attitudes of registered nurses regarding the prevention of HIV and AIDS transmission should be identified. Thus, it is important to survey the knowledge and attitudes of nurses in healthcare institutions related to the prevention of HIV and AIDS transmission. The main goal of the study was to explore and describe the knowledge and attitudes of registered nurses in public hospitals related to the prevention of HIV and AIDS transmission. The secondary objective was to develop in-service education guidelines for registered nurses in public hospitals to optimise both personal and occupational prevention measures relating to HIV and AIDS transmission. The research was conducted using a quantitative, explorative, descriptive and contextual design. The purposive sampling method was used to select the participants and a self-administered questionnaire was used to collect data. This data was analysed by inferential statistics and descriptive statistics and areas of deficits concerning knowledge and negative attitudes were identified. In this study there were deficits concerning the knowledge and negative attitudes regarding the prevention of HIV and AIDS transmission to a greater or lesser degree in all the subgroups of the questionnaire. In general, the registered nurses with the attendance of HIV and AIDS training program, experience in caring for HIV and AIDS patients made the level of certain knowledge related to the prevention of HIV and AIDS transmission different; Working experience as a registered nurses and the attendance of HIV and AIDS training programmes did not make attitudes towards the prevention of HIV and AIDS transmission significantly different. The registered nurses with experience of caring for HIV and AIDS patients had more positive attitudes than those without the experience. This information was used to compile in-service education guidelines for registered nurses concerning the prevention of HIV and AIDS transmission. The in-service education guidelines will be given to clinical facilitators at public hospitals. It is envisaged that this will guide them as to what to include in their in-service education programmes concerning the prevention of HIV and AIDS transmission for registered nurses.

  • Description: Scientific discourse allows for the calculation of negative outcomes attendant on conception and birth during adolescence, thereby producing a discourse of risk. The management of risk allows for the deployment of governmental apparatuses of security. Security, as outlined by Foucault, is a specific principle of political method and practice aimed at defending and securing a national population. In this paper I analyse how techniques of security are deployed in the interactions between health service providers and young women seeking contraceptive and reproductive assistance at a regional hospital in South Africa, and how racialised and gendered politics are strategically deployed within these techniques. Security combines with various governmental techniques to produce its effects. The techniques used in this instance include pastoral care, liberal humanism, the incitement to governmental self-formation, and, in the last instance, sovereign power.

  • 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 moni-tor, control, and secure them. Network security involves the creation of large amounts of information in the form of logs and messages from a number of diverse devices, sensors, and gateways which are often spread over large geographical areas. This makes the monitoring and control difficult, and hence poses security problems. The aggregation of information is necessary in information audits, intrusion detection, network monitoring and management. The use of different platforms and devices complicates the problem, and makes aggregation more difficult. Network security administrators and security researchers require aggregation to simplify the analysis and comprehension of activity across the entire net-work. Centralised information aggregation will help deal with redundancy, analysis, monitoring and control. This aids the detection of wide spread attacks on global organisational networks, improving intrusion detection and mitigation. This paper discusses and motivates the need for central-ised, cross platform information aggregation in greater detail. It also sug-gests methods which may be used, discusses the security issues, and gives the advantages and disadvantages of aggregation.

  • Description: This thesis presents for the first time a critical reading edition of all known poems by N. H. Brettell. It makes no claim to being definitive, nor does it attempt to establish a final text. It represents merely the best thinking of the editor. Brettell printed and circulated his poetry primarily in hand-made illustrated volumes in a process reminiscent of the scribal publication of the seventeenth century. Only 137 of his 206 extant poems were commercially published during his lifetime. In this study all known printed versions of Brettell's poetry whether in privately printed or commercially published form were examined. All variant readings were recorded and are shown. Wherever possible the relationships between texts are also noted. The poems in this edition are ordered in each case according to the version in the latest datable privately produced collection. The commentary and critical introduction were compiled with the general reader in mind. No previous familiarity with southern African fauna and flora is assumed: animals, birds and insects are described and their scientific names supplied. Expressions current in ordinary British or South African English and present in non-specialist dictionaries are not glossed, but archaic and dialectal forms felt to require explication are briefly explained. So too are less familiar South African dialectal expressions which have been assimilated into the South African English lexicon. Intertextual, Christian and mythological references, both African and Western, are annotated in an attempt to make such references accessible to readers who may not share Brettell's cultural background. The intention is to close the changing distance between the text and the audience. An essay discussing the merits, potential and limitations of electronic scholarly editing is included as part of the textual introduction. A CD-Rom containing Brettell's watercolour illustrations in his privately produced collections and audio-clips of him reading his poetry accompanies this thesis.

  • Description: This study examines the prominence of the term governance and its use in multilateral organisations, in particular the New Partnership for African Development. It argues that the term governance is contentious and needs to be reviewed. This is in light of the elevation of governance as a requisite for development, which has come about through the development of NEPAD. This is primarily a study on the position of the state in multilateral regimes and how governance will affect the state and non-state actors. The politics in and around governance are therefore important in any assessment of African development as governance becomes a developmental necessity. The African Rennaisance and African Union have become ‘beacons of hope’ for Africa and these have been discussed here. We can see NEPAD as a historical development that fits into the African Renaissance. This has been a mechanism to ensure state survival and the states that drive NEPAD have played a significant role in providing legitimacy to Africa’s calls for development. This thesis attempts to explain the shift in developmental policy in that NEPAD has seemingly become the first African development strategy that has the support of the West. Through this thesis, we will examine the role that the Post Washington consensus has played in getting this phase of African development started. What becomes significant here is the way in which governance has been accepted as the gauge for support in development. This study therefore aims to offer a means by which to analyse governance in multilateral organisations. As the term is contentious, three paradigms on governance will be provided in order to refine governance in such a way that it can be applied in analysis. This thesis shows that governance can be refined into corporatist, prebendal and conciliar forms. The form of governance that NEPAD will take has implications for the type of reconfiguration of the state brought about by governance.

  • Description: The post-apartheid government of South Africa has committed itself to achieving fundamental transformation of the education system. The government has adopted policies and measures that aimed to bring about the goals of equity and redress, and to enhance democracy and participation of all groups in development and decision making processes at all levels. It is acknowledged that the democratic government has accomplished a lot in education within this short period and has made numerous strides in enhancing equity, redress and social justice; providing high quality education for all the people of South Africa; bringing about democratisation and development; and enhancing effectiveness and efficiency. However, despite these apparent achievements, this study shows that there have been a number of setbacks and contradictions in the policies which have affected the process of bringing about fundamental changes and transformation in the education sector. The setbacks and contradictions resulted from factors which have affected the type of policies developed to transform the education sector. They also affected the formulation and implementation of the policies, thereby limiting the achievements of the goals of transformation agenda in education. Hence, this study examined the politics of transformation and change in the education sector by examining the type of policies that have been put in place; their formulation, implementation and outcome. The main research questions are: • What kind or type of policies have been put in place to transform the education sector? • How and by whom were the policies formulated? • How are these policies being implemented and what have been the outcomes of the process? Transformation and in particular the policy process is beset with continuous debate, contestation and struggle for the success of ideas and interests which are pursued by individual actors, groups and policy networks through the institutions. During these different stages policies are modified, constituted and reconstituted. As a result, they give rise to intended and unintended outcomes which are likely to support or contradict the objectives of those policies. Hence, the process cannot be explained using only one approach or theory. Therefore, this study has been situated in ideas, group and network and institutional approaches or theories to examine the factors that have affected education policies, their formulation and implementation and the overall transformation of education in South Africa. It contends that policy change and variation result from interaction of ideas and interests within patterns of group and policy networks and preset institutions. The study adopts qualitative interpretive methodology in order to question, understand and explain institutions; interests groups and ideas; socio economic and power relations involved in the process. It also appraises the framework for action. In addition to conducting literature review, unstructured interviews were held with officials from provincial and national Departments of Education, members of national and provincial legislatures, principals, teachers, members of school governing bodies, learners, Non-governmental organisations, Community based organisations, Faith based organisations, teachers’ and workers’ unions. Observations were made during meetings of school governing bodies. The study draws reference from the Eastern Cape Province between 1994 and 2002 and looks at the school level (Basic and Further Education levels). Reference is also made to selective policy instruments namely, the South African Schools Act (SASA) (1996), Curriculum 2005 and Norms and Standards for School Funding (1999). Overall, the findings of the study have shown that various factors have led to setbacks and contradictions in the policies that were adopted in education. They have also affected the formulation and implementation of the policies, hence exerting certain limitations on the achievements of the goals of transformation in education. The factors identified in the findings are the outcome of the negotiated settlement and subsequent changes made by the apartheid government in education before the 1994 elections; constraints and unequal participation of different groups in education policy development in various established structures and avenues; drawbacks in the implementation of education policies by decentralised structures and agents at various levels. This was exacerbated by lack of capacity, lack of adequate resources, lack of commitment and will among some of the civil servants coupled with corruption and mismanagement. The legacy of apartheid and the homeland governments, together with existing backlogs added another layer. Consequently, there were challenges in the economic policy which led to inadequate funding for education. The findings of this study show that competing ideas and interests advanced by groups and networks have impact on decision making, policy content and implementation. Therefore, some policies will reflect and maintain the interests of those individual actors, groups and policy networks that exerted most influence. The findings also reveal that institutional norms and rules, inadequate resources, lack of capacity and skilled human resources and economic environment, constrain decision making, policy content and implementation.
