- Description: The aim of the present research is to investigate three factors, namely perceptions of fairness in intergroup situations, ingroup identification and spatial dimensions that are assumed to contribute to why individuals participate in violence against the police in soccer stadiums. In Study 1 perceptions of fairness, identification and spatial perspective were manipulated and the results indicated a significant interaction effect between identification and spatial perspective. This interaction effect had a significant influence on negative behavioural tendencies towards police. In Study 2, identification and spatial perspective were manipulated and once again the interaction effect between identification and spatial perspective was found. A main effect of identification was found in that participants who identified lower with fans showed significantly more positive attitudes towards police. The results of the two studies highlight the importance of looking beyond the inherent nature of the crowd itself when analysing situations of police/fan conflict, and also the need to further investigate the spatial dimension and how it influences social judgment and decision making.

- Description: Debates about the structures and processes of globalisation - along with those of localisation - have important implications for the discipline (or is it still a field?) of media studies. The first implication, framed as a counter-hegemonic resistance to what some might consider to be the totalising tradition of Western media studies scholarship, is that we can no longer continue to look only to Western centres of academe for intellectual edification. The need for a critical deconstruction of Euro-American intellectual centrism, and the need for recognising and thus reconstructing a truly transcultural onto-epistemological agenda for media studies, has become more urgent than ever before.

- Description: This study involves the application, interpretation and utilization of regional geochemical data for target generation in the North West Province, South Africa. A regional soil geochemical survey programme has been carried out by the Council of Geoscience South Africa since 1973. A number of 1:250 000 sheet areas have been completed, but there are no interpretative maps which could aid in mineral exploration and other purposes. In order to utilize the valuable and expensive data, the project was motivated through data acquisition and interpretation to generate exploration targets. The study area is confined to Mafikeng, Vryburg, Kuruman and Christiana in the Northwest Province, where potential exploration and mining opportunities exist in areas of great geological interest. These include geological events such as the Bushveld Complex, the Kalahari manganese field and the Kraaipan greenstone belts. The aim of this project was to utilize geochemical data together with geophysical and geological information to verify and identification of possible obscured ore bodies or zones of mineralization, and to generate targets. Another objective was the author to be trained in the techniques of geochemical data processing, interpretation and integration of techniques such as geophysics, in the understanding of the geology and economic geology of the areas. Approximately 5 kg of surface soil was collected per 1 km2 by CGS from foot traversing. Pellets of the samples were prepared and analyzed for TiO2, MnO and Fe2O3, Sc, V, Cr, Ni, Co, Cu, Zn, As, Y, Ba, Nb, Rb, Th, W, Zr, Pb, Sr and U using the simultaneous wavelengthdispersive X-ray fluorescence spectrometer technique at the Council for Geoscience, South Africa. For each element the mean +2 standard deviations were used as a threshold value to separate the negative from the positive anomalies. The integration of geological, geophysical and geochemical information was used to analyze and understand the areas of interest. A number of computer programmes were extensively used for data processing, manipulation, and presentation. These include Golden Software Surfer 8®, Arc-View 3.2a®, TNT-Mips®, JMP 8 ®, and Microsoft Excel®. Through geochemical data processing and interpretation, together with the low resolution aeromagnetic data, gravity data and geological data, seven (7) exploration target areas have been generated: These have been numbered A to G. It is concluded that there is good potential for Cr, PGMs, vanadium, nickel, iron, copper, manganese, uranium and niobium in the targets generated. The results provide some indication and guide for exploration in the target areas. In Target A, Cu, Cr, Fe, Ni and V anomalies from the lower chromitite zone of far western zone of the Bushveld Complex, which has be overlain buy the thick surface sand of the Gordonia Formation. Target B occurs over the diabase, norite, andesitic lava and andalusite muscovite hornfels of the Magaliesberg Formation. This target has the potential for Cu, Fe and Ni mineralization. The felsic rocks of the Kanye Formation and the Gaborone Granite in target C have shown some positive anomalies of niobium, uranium, yttrium and rubidium which give the area potential for Nb, REE and U exploration. Target D is located on the Allanridge Formation, and has significant potential for Ni-Cu mineralization, and is associated with the komatiitic lava at the base of the Allanridge Formation in the Christiana Area. The light green tholeiitic, calc-alkali basalt and andesitic rocks of the Rietgat Formation are characterized by a north-south trending yttrium anomaly with supporting Ba and Y anomalies (Target E). This makes the area a potential target for rare earth elements. Calcrete on the west of the Kuruman has a low b potential target for vanadium. It is believed that the area might be potential for potassium-uranium vanadate minerals, carnotite which is mostly found in calcrete deposits. This study has proved to be a useful and approach in utilizing the valuable geochemical data for exploration and future mining, generated by Council for Geoscience Science. It is recommended that further detailed soil, rock and geochemical surveys and ultimately diamond drilling be carried out in the exploration target areas generated by this study.

Interrogating gender constructions in the Daily Sun: an analysis of the coverage of the 'Charter for a Man' campaign against gender violence between November and December 2007

- Description: The study seeks to interrogate the gender constructions in the Daily Sun’s “Charter for a Man” campaign which ran from 7 November to 7 December 2007. It coincided with the 16 Days of Activism against gender violence and was designed to lobby support for this campaign and discourage men from physically abusing women. The “Charter for a Man” listed nine principles that signatories were to abide by. It included a section to be signed by men to be submitted to and collected by the Daily Sun. The campaign was constructed as an intervention into the issue of gender violence. Consequently, the 30 news stories, four editorial pieces and 11 letters to the editor that were published during the campaign period make up the textual data analysed in the study. The news stories consisted of testimonies from abused women and some women abusers. In addition, celebrity signatories were selected to endorse the campaign and encourage other men to follow suit. In the editorials, the campaign was consistently flagged as a nation building initiative which all men were supposed to support. The letters to the editor consisted of readers who either supported or rejected the campaign. The study takes place against the context of a patriarchal society characterised by high levels of violence. Given this scenario, the study is informed by a concern with gender justice and therefore considers whether such a campaign, ostensibly aimed at eradicating gender violence, has the potential of being transformative of gender inequalities. The study set out to establish the kinds of masculinities and femininities that were variously constituted in the campaign as well as the gender discourses that were privileged. It is informed by the theories of feminist poststructuralism and Foucault’s conceptualisation of discourse. As the campaign is the initiative of a tabloid newspaper, it is also considered within the framework of newspaper campaigns and arguments about tabloids and the public sphere. As text based research, the study employs critical discourse analysis as a qualitative procedure of textual analysis. It makes use of an eclectic approach to textual analysis that draws on linguistics, narrative and argumentation. The texts are analysed according to the categories of news texts contained which includes the Charter itself, signatory articles, testimonies, vox pops and letters to the editor. The overarching theme of nationhood projected in the editorials and other categories is also discussed as part of the analysis. The study concludes that the Daily Sun campaign might be a seemingly progressive action at first glance. However, it does not challenge the existing gender order but rather maintains and sustains patriarchal attitudes through the repeated representation of women as weak and in need of patronage and men as their protectors and providers. In some instances, women are constructed primarily as sexual beings as their physical attributes are emphasised, while men are constructed as working class citizens and rational beings. The study therefore proposes that the Daily Sun fails as an alternative public sphere that might make visible the concerns of women as a marginalised group in society. The campaign, it is argued, is self-serving in its promotion of the Daily Sun’s image as the “People’s Paper” rather than serious concerns about gender violence.

- Description: We studied the effects of mixed honeybee colonies of Apis mellifera and Apis cerana on the intraspecific and interspecific recognition of female brood stages in the honeybees A. cerana and A. mellifera by transferring brood combs between queenright colonies. In the intraspecific tests, significantly more larvae were removed in A. cerana than in A. mellifera, whilst significantly fewer eggs and pupae were removed in A. cerana than in A. mellifera. In the interspecific tests, A. cerana colonies removed significantly more larvae and pupae of A. mellifera than the same brood stages of A. cerana were removed by A. mellifera. We show there are highly significant differences in both intraspecific and interspecific brood recognition between A. cerana and A. mellifera and that brood recognition operates with decreasing intensity with increasing developmental age within species. This suggests that worker policing in egg removal is a first line of defense against heterospecific social parasites.

- Description: Service delivery is critical to the customer’s perception of value and is core to the success of an organisation. Excellent customer service incorporates the critical aspects of: expedient service delivery; open and honest communication; individual, personalised service; engendering customer loyalty; problem-solving; under-promising and over-delivering; meeting and exceeding expectations; efficient use of infrastructure, systems and procedures to facilitate efficient operations and, in particular, effective use of knowledge management with a focus on customer lifecycle care (Kingstone, 2004, 2005; Zarbock, 2006). Best-practice organisations now use Customer Relationship Management (CRM) programmes that are customer-centric based in order to ensure excellent customer service delivery. Recently, organisations such as Tesco and Nordstrom have adopted customer-centric CRM successfully, providing concrete proof that this CRM model is sustainable and that it produces the highly lucrative win-win benefits which organisations seek (Beasty, 2005; Hallberg, 2001:19; Gratehouse, 2002; Rowe, 2002). 5 Glossary • Continuous improvement: an approach to improving performance which assumes more and smaller incremental improvement steps (Pycraft, Singh, Phihlela, Slack, Chambers, Harland, Harrison, & Johnston, 2002); • Connectivity: the ability to communicate with another system or piece of hardware or software, or with an internet site (Encarta World English Dictionary); • Customer-centric: the use of every touch-point to stimulate interest, close business, satisfy a need or demonstrate commitment to the customer relationship (Gianforte, 2005); • Customer expectations: the customer's perception of the quality of service (LeBoeuf, 1991) and value (Thompson, 2004); • Customer Experience Management: managing customer interactions to build brand equity and long-term profitability (Thompson, 2006a); • Customer lifecycle care: to ensure that every touch-point fulfils its value-potential, regardless of whether the interaction happens in marketing, sales or customer service (Gianforte, 2005); • Customer loyalty: customer’s attitudes and behaviour relating to their perception of value at every touch-point where they feel welcome, important and valued (Thompson, 2004); • Customer Relationship.

- Description: While there is a fair amount of work on determinants of demand for the live performing arts, results have often been contradictory with little explanatory power. This may be because of the difficulty in describing the attributes of a performance, particularly in terms of its quality, and the heterogeneity of consumer preferences. This article uses conjoint analysis, also called choice experiments, to investigate the impact of the attributes of live theatre performances on demand, using data collected from 483 randomly chosen attenders at live theatre performances at the 2008 South African National Arts Festival. Attributes include the type of cast (professional, semi-professional or amateur), reputation of the producer/director, the context or setting, production type and ticket price of the show. Results largely support the a priori expectations based on the results of other demand studies. For example, it is found that the age of consumers affects the type of show chosen, that utility and willingness to pay increase for shows with professional and semi-professional casts and that 93% of the potential audience prefer shows with a South African context. It is concluded that the method could prove useful to both event organisers and policy makers, especially where the goal is to broaden access to the arts.

- Description: The site of this research is the Kigali Institute of Science and Technology (KIST). The research was undertaken to investigate first year students' perceived English language needs in order to study successfully at KIST. The research was intended to pave the way for differentiated English language syllabuses for students of varying English proficiency. It sought to answer the following questions: (1) what are students' perceived language needs in order to study through the medium of English at KIST? (2) To what extent does the current English language programme address these perceived needs? And (3) what are the differences in students' perceived language needs at different levels of proficiency? The research was carried out in an interpretive paradigm using both qualitative and quantitative methods. It took the form of a case study utilising questionnaires to collect data. Questionnaires were administered to students, mainstream subject lecturers and English lecturers. The student sample consisted of 212 students chosen from the four previously identified levels of proficiency (beginner, elementary, intermediate and advanced). The lecturer samples consisted of seven subject lecturers and eleven lecturers in English. The research tools used to collect data were administered questionnaires and document analysis. The chi-square statistical test was used to analyse quantitative data especially in establishing differences that appeared between dissimilar proficiency levels. Findings have shown that, although English is no longer a credit-bearing course, students are still interested in learning it. Students expressed a high positive perception for learning language structures, listening and speaking, and a need for reading and writing. However, although it was possible to establish stakeholders' (students, subject lecturers and lecturers in English) perceptions of students' needs, it was not easy to establish what students' real needs and difficulties in English are. Attempts to get valid answers to my questions were not conclusive. Although this research has implications for the future of English language teaching/learning at KIST there is a need for further investigation of students' needs. An important starting point would be to begin a debate at KIST about the whole issue of students' needs. Such research would exploit research tools/methods not used in this research (e.g focus group interviews and observations).

- Description: The site of this research is the Kigali Institute of Science and Technology (KIST). The research was undertaken to investigate first year students' perceived English language needs in order to study successfully at KIST. The research was intended to pave the way for differentiated English language syllabuses for students of varying English proficiency. It sought to answer the following questions: (1) what are students' perceived language needs in order to study through the medium of English at KIST? (2) To what extent does the current English language programme address these perceived needs? And (3) what are the differences in students' perceived language needs at different levels of proficiency? The research was carried out in an interpretive paradigm using both qualitative and quantitative methods. It took the form of a case study utilising questionnaires to collect data. Questionnaires were administered to students, mainstream subject lecturers and English lecturers. The student sample consisted of 212 students chosen from the four previously identified levels of proficiency (beginner, elementary, intermediate and advanced). The lecturer samples consisted of seven subject lecturers and eleven lecturers in English. The research tools used to collect data were administered questionnaires and document analysis.

- Description: This study used diagnostic tests, questionnaires and interviews to investigate explore teachers’ subject content knowledge (SCK) and pedagogical subject knowledge (PCK). It also explored teachers’ and learners’ misconceptions within the topic of graphicacy and how teachers’ SCK and PCK possibly affect learner achievement. A small sample of teachers were drawn from the Keiskammahoek region; a deep rural area of the Eastern Cape. These teachers were part of the Nelson Mandela Metropolitan University (NMMU) Amathole Cluster Schools Project who were registered for a three-year BEd (FET) in-service programme in mathematics education. As part of the programme they studied mathematics 1 and 2 at university level and received quarterly non-formal workshops on teaching mathematics at FET level. The findings of this study suggest that teachers with insufficient SCK will probably have limited PCK, although the two are not entirely dependent on each other. In cases where teachers’ displayed low levels of SCK and PCK, their learners were more likely to perform poorly and their results often indicated similar misconceptions as displayed by their teachers. This implies that we have to look at what teachers know and what they need to know in terms of SCK and PCK if we are to plan effectively for effective teacher development aimed at improving learner performance.

- Description: Packet demultiplexing and analysis is a core concern for network secu-rity, and has hence inspired numerous optimisation attempts since their conception in early packet demultiplexing filters such as CSPF and BPF. These optimisations have generally, but not exclusively, focused on improving the speed of packet classification. Despite these im-provements however, packet filters require further optimisation in order to be effectively applied within next generation networks. One identified optimisation is that of reducing the average path length of the global filter by selecting an optimum filter permutation. Since redundant code generation does not change the order of computation, the initial filter order before filter optimisation affects the average path length of the resultant control-flow graph, thus selection of an optimum permutation of filters could provide significant performance improvements. Unfortu-nately, this problem is NP-Complete. In this paper, we consider using Genetic Algorithms to’breed’an optimum filter permutation prior to re-dundant code elimination. Specifically, we aim to evaluate the effec-tiveness of such an optimisation in reducing filter control flow graphs.

- Description: Efforts to discover an efficient yet environmentally friendly mode of metal nanoparticle (NP) synthesis are increasing rapidly. A ‘green’ route that avoids the high costs, toxic wastes and complicated protocols associated with chemical synthesis methods is therefore highly sought after. A biologically based protocol will provide the possibility of gaining control over the mechanism merely by manipulating the experimental conditions of the system. Given that the properties of nanoparticles are highly dependant on the morphology of the particles themselves, this mechanistic control will provide significant industrial advantages with regards to tailoring specific properties of the nanoparticles produced. The key objectives of this study were to: a) determine whether a consortium of sulfate-reducing bacteria was capable of platinum nanoparticle synthesis, b) elucidate the bioreductive, enzymatic mechanism responsible, and c) attempt to control the morphologies of the particles produced. A consortium of sulfate-reducing bacteria (SRB), isolated from sewage sludge, was used in these investigations due to the advantages a consortium provides in comparison to pure cultures. The syntrophic relationships established within the constituent species not only prevent the growth of contaminant microbes, but increases the oxygen-tolerance of the system as a whole. The sulfate-reducing consortium was shown to possess an aerobic mechanism for Pt(IV) reduction which, though different from the anaerobic bioreductive mechanism previously identified in literature, did not require an exogenous electron donor. It was demonstrated that the Pt(IV) ion becomes reduced to Pt(0) via a two-cycle mechanism involving Pt(II) as the intermediate. Further investigation elucidated the reduction of Pt(IV) to Pt(II) to be dependant on a novel Pt(IV) reductase which becomes upregulated in the presence of Cu(II), while the reduction of Pt(II) to Pt(0) occurred by means of a periplasmic hydrogenase. To our knowledge, this is the first time a coupled mechanism for Pt(IV) reduction by micro-organisms has been proposed. A cell-free, crude protein solution from the consortium produced both geometric and irregular platinum nanoparticles. The wavelength of 334 nm was chosen as a nonquantitative indicator of Pt(0) nanoparticle formation over time. The optimum conditions for nanoparticle synthesis were pH 9.0, 65 ˚C and 0.75 mM Pt(IV) as H2PtCl6 salt. In the absence of a buffer a Pt(IV) concentration > 1 mM resulted in the precipitation of protein-nanoparticle bioconjugates, due to unfavourable acidic conditions. This demonstrated that the nanoparticles were binding to and becoming stabilised by general protein in the cell-free solution. Upon addition of a sodium-bicarbonate buffer, a general increase in Pt(IV) reduction to Pt(II) was observed. The addition of the buffer also resulted in an unexplained change in particle morphology and for this reason was not used in subsequent investigations. Polyvinylpyrrolidone (PVP) was shown to compromise the reduction rate of the Pt(IV) ion by SRB cells. The presence of extracellular NP’s was suggested by the colour of the supernatant turning brown and the A334 increasing over time. Attempts to visualise the particles by transmission electron microscopy (TEM) resulted in an unexpected phenomenon where nanoparticles could be observed to form dynamically upon irradiation by the electron beam. Extended irradiation by the electron beam also resulted in structural changes of the particles occurring during observation. An increase in temperature was shown to increase the reduction rate which in turn resulted in particles decreasing in size. The starting pH was shown to have a significant effect on the reduction rate and particle morphology although specific trends could not be identified. In conclusion, the cell-soluble extract from the sulfate-reducing consortium investigated, is capable of Pt(0) nanoparticle synthesis. Precise control over the particle morphology was not attained although the mechanism was further clarified and optimal conditions for nanoparticle synthesis were determined.

- Description: The purpose of this research was to investigate what is involved in IT Service Management and how the NMMU can implement it to improve the quality of IT service support and service delivery. The IT Service Management approach was investigated but the main focus was on the Service Support and Service Delivery in the ITIL framework. Higher Education was analyzed to try and measure the maturity level of the ITIL process implementation to see where Higher Education in South Africa is and to determine the gaps. Findings from the empirical study will be presented and recommendations highlighted to Top management and the IT department in order to promote and improve the quality of the IT service being delivered to users and customers. The data was collected and administered by means of a structured questionnaire based on the ITIL Service Capacity Maturity Model and Rick Leopoldi’s alternative Maturity Assessment method. An Association of South African University Directors of Information Technology (ASAUDIT) questionnaire on Service Management was also used to supplement the questionnaire. It was discovered that the implementation of ITIL in most organizations brought about improvements and benefits in the quality of the IT service being delivered.

- Description: This Master’s thesis discusses the investigation of autoignition (knock) of air-fuel mixtures in internal combustion engines (type EA 827; 1.6 and 1.4 l) under hot start conditions. Chapter Three comprehensively reviews literature on fuel characteristics; specifically boiling point, chemistry and the difference between the Research and Motor Octane Number (RON and MON). Furthermore different types of autoignition are discussed with regards to their detection and assessment in the chapter. The subsection on engine management looks at possible methods of altering and eliminating autoignition. Chapter Four details the equipment used to obtain data and measurements, as well as the signal conditioning of the spark and injector signal. Chapter Five discusses the actual results obtained during summer testing of the different methods of altering and eliminating autoignition in an internal combustion engine, as derived from the theories presented in Chapter Three. The summer tests finally verified the new application level and showed that only a reduction in the quantity of fuel injected can eliminate autoignition. However, a slight decrease in heat release does cause an increase in start time. In Chapter Six, based on the test results, a simulation model which calculates the probability of autoignition in a 1.4 l (Econo) engine during hot start conditions in Matlab/Simulink was developed. This simulation model satisfactorily verified test results.

- Description: In order to investigate the influence of parasitic resistances, saturation current and diode ideality factor on the performance of photovoltaic devices, parameter extraction routines employing the standard iteration (SI) method and the particle swarm optimization (PSO) method were developed to extract the series resistance, shunt resistance, saturation current and ideality factor from the I-V characteristics of solar cells and PV modules. The well-known one- and two-diode models were used to describe the behavior of the I-V curve and the parameters of the models were determined by approximation and iteration techniques. The SI and the PSO extraction programmes were used to assess the suitability of the one- and the two-diode solar cell models in describing the I-V characteristics of mono- and multicrystalline silicon solar cells, CISS- and CIGSS-based solar cells. This exercise revealed that the two-diode model provides more information regarding the different processes involved in solar cell operation. Between the two methods developed, the PSO method is faster, yielded fitted curves with lower standard deviation of residuals and, therefore, was the preferred extraction method. The PSO method was then used to extract the device parameters of CISS-based solar cells with the CISS layer selenized under different selenization process conditions and CIGSS-based solar cells with varying i-ZnO layer thickness. For the CISS-based solar cells, the detrimental effect of parasitic resistances on device performance increased when the temperature and duration of the selenization process was increased. For the CIGSS-based devices, photogeneration improved with increasing i-ZnO layer thickness. At high forward bias, bulk recombination and/or tunneling-assisted recombination were the dominant processes affecting the I-V characteristics of the devices. v Lastly, device and performance parameters of mono-, multicrystalline silicon and CIS modules derived from I-V characteristics obtained under dark and illuminated conditions were analyzed considering the effects of temperature on the performance of the devices. Results showed that the effects of parasitic resistances are greater under illumination and, under outdoor conditions, the values further declined due to increasing temperature. The saturation current and ideality factor also increased under outdoor conditions which suggest increased recombination and, coupled with the adverse effects of parasitic resistances, these factors result in lower FF and lower maximum power point. Analysis performed on crystalline silicon and thin film devices utilized in this study revealed that parameter extraction from I-V characteristics of photovoltaic devices and, in particular, the implementation of PSO in solar cell device parameter extraction developed in this work is a useful characterization technique.

- Description: Flooding has been identified as the predominant, environmental generator of food emergencies. Climate change and climate variability have been blamed for these extreme weather events, which are envisioned to affect the future food security and nutritional status of populations across the African continent. It is thus expected that these weather phenomena will continue to increase in frequency and intensity as climate change progresses. Already, climate change has had a dramatic effect on the natural world with increased desertification, warming oceans, rising temperatures and changing weather patterns. In turn, this has affected agriculture and fishing, which subsequently determines the availability of food. On the contrary, weather alone, is not the sole contributing factor to problems that are associated with food security/insecurity. Elements embedded within a political, social, economical, and/or other, context also serve to contribute to how a population or individual experiences food security. It is therefore imperative that these aspects from the social or developmental arena are considered in conjunction with aspects from the natural or environmental sciences. Such a holistic approach to subjects relating to climate change and development will eventually lead to the realisation of sustainable development, which in turn serves to protect human security in the long-term. The research was primarily directed at examining how flooding affects food security and what can be done to avoid, or cope with, a potential food crisis. The above-mentioned social and developmental features shaped the scope of this research, giving rise to an investigation which transcended the confines of flooding as an independent cause and consequence of food insecurity. With East Africa as a focal point, Mozambique and Zambia emerged as the most affected countries with millions of people affected by these devastating waters in 2000 and 2007, respectively. Due to the past nature of the events, it was most appropriate to utilise statistics from sources such as existing databases, reports and articles. Some of the topics that were included in the investigation examined the causes and consequences of the flooding and the management of these disasters. These topics were scrutinised using both qualitative and quantitative dimensions of research, so that an interesting and viable study could be undertaken. ii The research found that frequent and severe flood disasters increase a population‟s vulnerability to food insecurity, as a wide variety of assets, structures and infrastructures are destroyed. However, with careful management, planning and adaptation, many of these unwanted consequences can be avoided or swiftly overcome. Both Mozambique and Zambia were found to be countries that were determined to overcome the barriers associated with climate change and its subsequent extreme weather events. This positively indicated that they were committed to the development process and the wellbeing of their populations. Apart from introducing the topic surrounding the influence of flooding on food security in East Africa, one of the main goals of this research was to gather recommendations and suggestions for avoiding or managing issues that could hamper food security. This ultimately forms an important source of reference for governmental and non-governmental institutions dealing with flooding and food security. Even though Mozambique and Zambia were chosen as the cases for investigation, many of the recommendations can be adapted and applied to countries world-wide.

- Description: This dissertation focuses on the investigation of the microstructures of two nuclear grade matrix graphites. These graphites were intended for use in the core components of a high temperature test reactor (HTTR) of the pebble bed modular reactor (PBMR) design. The graphites were provided in the form of fuel spheres and a reflector block. The techniques used in the analysis of the materials include fracturing, etching, scanning electron microscopy (SEM), nano-indentation, x-ray diffraction (XRD) and transmission electron microscopy (TEM). The microstructures of the materials were characterized successfully. The fuel sphere material consisted of a high concentration of curved graphite flakes and grains in contact with turbostratic matrix graphite. The well graphitized flakes and grains were polycrystalline in nature. Delamination cracks were prevalent in the graphite crystallites. There was no significant difference in the microstructures of the center, interior and surface regions of the fuel sphere material. No evidence of amorphous carbon or resin residues was found. The reflector material consisted of a low concentration of graphite crystallites embedded within turbostratic matrix graphite. Delamination cracks were observed within the graphite crystallites, and many cavities were present in the material. TEM observation also revealed the presence of diamond crystallites. It was concluded that the fuel sphere graphite was most probably suitable for use as is, provided that the material also possessed other required properties for use in a HTTR. The reflector material however was considered to be unsuitable for use in a HTTR. It was thus suggested that the reflector material could be made more suitable by sufficient graphitization of the turbostratic graphite which formed the bulk of the material.

- Description: Using a multivariate cointegration and error correction modelling framework, with data from the SACU countries, this paper tested two rival theories on the effect of financial integration (FI), that is whether FI is a complement or a substitute to financial development (FD). Financial integration is a complement where it helps to boost domestic FD through greater competitive pressures on financial intermediaries, and encourage international good practices in accounting, financial regulation and supervision. It is a substitute where FI renders the local financial system irrelevant or causes it to deteriorate. Overall, the empirical analysis finds strong evidence of a long-run relationship between FD and FI across the SACU countries. The results show that causality runs in both directions between FD and FI across the SACU countries with the exception of Lesotho where the causality runs mainly from FI to FD. No consistent effect of FI on FD (or the reverse) emerged from the empirical results in this sample. The results were also affected by the measurements used for the capital stock and FD. These results do not support any one-size-fits-all policy approach to stimulating FD or harnessing the benefits of FI, rather, they suggest that country specific aspects of the financial system should be paramount when analysing the impact of FI on FD.

- Description: The scourge of HIV/AIDS (human immunodeficiency virus/acquired immune deficiency syndrome) is most prevalent in southern Africa. South Africa has the highest number of people in the world living with HIV/AIDS and a prevalence rate of over 30 % for females presenting at antenatal clinics. There are now almost five million orphans within southern Africa, as a result of AIDS deaths of one or more or their parents. AIDS-related mortality and morbidity of care-givers may lead to increased reliance on wild sources of animal protein by surviving children. This increase in hunting pressure has unknown, but potentially important impacts on local animal populations.

- Description: The distinctive features of inflation targeting include the publishing of the formal (official) target band or point target for the rate of inflation at one or more time horizons and the explicit confirmation that low and steady inflation is the long-run objective of monetary policy. There are four main preconditions of inflation targeting: 1) an independent central bank that is free from fiscal and political pressures; 2) a central bank that has both the ability to forecast inflation and the capability to model inflation data; 3) the presence of fully deregulated prices and an economy that is affected by changes of commodity prices, as well as exchange rates; and 4) the presence of sound banking system and well developed capital markets. In most developing countries, the use of seigniorage revenues as a source of financing government debts, the lack of commitment by monetary authorities to low inflation as a primary goal, the absence of the central bank’s functional independence, and of powerful models to make domestic inflation forecasts, prevent the satisfaction of these preconditions. This dissertation investigates the extent to which Malawi meets the preconditions for inflation targeting by comparing the situation in that country to other developing countries, which have already adopted the framework. Malawi is committed to the central bank’s functional independence as well as the pursuit of prudent fiscal policy measures for the attainment of low inflation. Despite the failure to meet all the preconditions, this study recommends that Malawi should adopt an inflation targeting framework due to the strength of commitment of the monetary authorities in satisfying these preconditions.
