- Description: This work addresses the role of mirroring and mirrors encountered while working with a patient obsessed with his appearance. At the same time, however, it also attempts to provide an understanding of the process of mirroring from the developing unborn child to the adult. It examines the womb as a reflective space, the mirroring role of the mother, psychological work as mirror work, the psychopathologies of disruptive mirroring and the nature of reflection as a story, confusion and a ghostly other, and finally, the relationship between mirror reflection and psychological life. What is examined and described in this process applies not only to the specific case in study but is relevant at a universal level to all of mankind regardless of race or religion. The case-study method was used to examine the process of therapy that took place over three months. The patient’s identifying data, reasons for referral, presenting problem, family background, basic personality, interpersonal relationships, mental state, diagnosis, dynamic formulation and rationale for psychotherapy were covered in detail. The process of psychotherapy over 27 sessions was recounted and discussed in detail. Theoretical understandings drawn on to facilitate an understanding of the case were from Davis and Walbridge on Winnicolt, Winnicot, Liedloff, Kay, Romanyshyn, Bettelheim, Schwartz and others. , Thesis (MA) -- Faculty of Humanities, Psychology, 1993

- Description: Because work is such a tremendous potential source of meaning in an individual’s life, techniques which turn career choice into technical talent matching are inadequate. The individual’s search for authentic meaning needs to be the focus of career counselling, but few approaches have been able to addressed this relationship between working and living. Major developments in career theory are reviewed to highlight the distinction between the more technical logical positivist and the phenomenological approaches. Super’s Career- Development Assessment and Counselling (C-DAC) model is described in detail as it is the first significant attempt to move beyond the technical approaches by incorporating developmental theory into career counselling and by stressing the role of counsellee readiness to use the information provided. However, especially in South Africa, any test-based approach to career counselling runs the risk of shifting the locus of control from the counsellee to the counsellor, so an autobiographical non-test approach, the life-line, is introduced to assist counsellees in their search for personal meaning without running the risks associated with test-based assessments. The life-line helps to contextualise the choice of work within the counsellee’s subjective life experience and turns career counselling into a shared search for a range of personal meanings rather than the provision, by the counsellor, of a limiting interpretation. Three case studies are presented to demonstrate the use of the life-line, and the conclusions arrived at are shown to be essentially1 similar to conclusions obtained from using the C-DAC battery. The advantages and limitations of the life-line are discussed and its ability to combat problems associated with school based career counselling is outlined as well as its usefulness with mid-life career changers, in cross-cultural contexts, and in group counselling. , Thesis (MA) -- Faculty of Humanities, Psychology, 1990

- Description: The Otjihase pyritic massive sulphide deposit occurs within a 10km thick metasedimentary sequence of the Kuiseb Formation. The Kuiseb metasediments were deposited within the Khomas Trough, which forms the southernmost rift of the intracontinental arm of the Damara orogen. Amphibolite units of the Matchless member at Otjihase have a MORB-type geochemical character and occur within the Kuiseb schists, about 200m above the ore zone. The Otjihase mine is the largest of many Besshi-type deposits that occur in close proximity to the Matchless amphibolites. A depositional environment in a rift, slightly more advanced than the present-day Red Sea is envisaged. The five parallel, ruler-shaped, mineralised shoots at Otjihase occur on the same stratigraphic level. They have a plunge of approximately 6° to the west and a dip of approximately 16° to the northwest. The largest and best mineralised, is the northernmost shoot (the Main Shoot) which is ±250m wide, up to 12m thick and has a known length of 7,5km. The large length/breadth ratio is ascribed to the original setting along faults and thickening of the ore zone during thrusting. Intense ductile deformation has affected the ore bodies, with isoclinal refolding, boudinaging, duplexes of more competent bands and smearing of the schists. Squeezing and remobilisation of the sulphides into the schistosity and low pressure pods has taken place. Successive folding and thrusting during the D2 deformational event resulted in the dominant structural style. Fold axes of drag folds plot onto a great circle in stereographic projection, indicating the formation of sheath folds. The axial planar cleavages of competent layers is steeper than the S(0,1) foliation and suggests a structural right way-up. The presence of chloritic alteration above the ore shoots, is suggestive of footwall alteration indicating that the sequence was overturned during the D1 deformational event. Ore zone lithologies include stringery-, massive- and semi-massive sulphides, mineralised magnetite- quartzites and disseminated sulphide mineralisation within quartz-biotite-chlorite schists. Chalcopyrite is the main economic mineral and mainly occurs as matrix to pyrite and in coarse-grained pods. Lithological and metal zoning within the Main Shoot is distinct and is an indication that the macroscopic shape of the orebody is largely unaffected by later ductile deformation. North-south trending normal faults of the Windhoek Graben have disrupted the continuity of the ore shoots. In section, the faults appear to have a listric shape. The major faults have pronounced scissor movements and as a result the dips of the blocks within fault zones are affected. , Thesis (MSc) -- Faculty of Science, Exploration Geology, 2021

- Description: The aim of this thesis is to promote the dramatological approach, as opposed to a literary critical one, for the analysis of dramatic texts for the purposes of staging. The reason for such a promotion is that the dramatological approach upholds the integrity of the text in interpretation for the performance text by its detailed and semiotic analysis. The focus of such an approach is on the analysis of discourse, that is a micro-proairetic approach (illuminating the extralinguistic action and interaction gained from speech events and deixis), rather than a macro-proairetic approach (that is, plot and story-line) which a literary critical approach would take into consideration. In Chapter one the focus is on the justification for the dramatological approach as well as a review of prominent literary criticism to the playwright’s work (used as an example of dramatic text in this thesis). Rather than the promotion of ordinary literary theory in relation to the need for a performance methodology, explanation for their negation is offered here. Chapter two focuses on the actual methodology of the dramatological approach. In section one of this chapter, we find that basic to dramatological methodology is the linguistic function appropriate to the dramatic: that is the semantic, rhetorical and pragmatic principles of dramatic dialogue. In addition, we find that it is a formal and systematic approach which imposes restrictions on dualisms thereby upholding the integrity of the text. Moreover, that it focuses on the “performative-deictic” character (that is extralinguistic, kinesic and indexical orientations) of the dramatic text - analysis of which is crucial for the purposes of staging. In this way, the analysis of the interpersonal, interactional and contextual areas of dramatic texts is promoted. Thus section one offers an overview of the analytical criteria appropriate to such investigation in order to illuminate dramatic discourse. Section two offers a guide to the application of the methodology, utilizing an extraction of text. Central to the application is the formation of a preliminary analytical ‘grid’ from the range of criteria discussed in section one; that is, how these may be put together. A micro-segmentation of text is utilized to illustrate the application of the methodology. Chapter three offers an application of the methodology to a whole text, that is The Dumb Waiter. The results and benefits for the theatre practitioner of such application are directly illustrated in the deictic (that is section one) and proairetic (that is section two) segmentations of the text since what the text and discourse signify is illustrated in a detailed manner as opposed to paraphrase. That is, the interpersonal, contextual and interactional levels of the drama are defined. From this, typologies of discourse, character and interrelationships are drawn, as well as a creation of the dramatic world (that is section three) constructed as a result of the discourse, interrelationships and dramatic action. Finally the Conclusion offers an evaluation of the dramatological approach by applying it to a practical situation for the theatre practitioner (that is, director or actor). , Thesis (MA) -- Faculty of Humanities, Drama, 1999

It will look at how and why metal binding takes place, known platinum group metal speciation will be included. Examples of how to improve metal binding efficiency will be discussed by stimulating ligand activity by polarisation. Various biotechnical options available, with emphasis placed on the use of the aquatic fern and algae will be given as examples of biological treatment of heavy metals in particular the aquatic fern Azolla. The method of standard preparation and the use of Inductively Coupled Plasma Emission Spectrophotometer (ICP) used for analytical analysis will be included so that consideration can be given to the collection of analytical data in the provision of evidence to support or provide a conclusion. The outcome of the test work utilising the aquatic plant Azolla has proven that it can be used to remediate platinum refinery effluent. This process can offer an alternative to the classical chemical method normally used, which is economically viable and environmentally friendly in comparison to the common methods of refinery effluent treatment. , Thesis (MSc) -- Faculty of Science, Biochemistry, Microbiology and Biotechnology, 200u

- Description: In order to understand the effects of metals contained in effluent and to define effluent quality suitable for safe discharge to natural water streams, it is essential to understand the effects of the interaction of metal ions with plants. The availability of metal ions and their ability to bind to plants are dependent on the chemical speciation of metals and on the biological factors governing the availability of metals within the plant cells. This thesis will address both aspects and thereby propose a combination of an appropriate chemical and biological approach to the investigation of bioaccumulation of the plant Azolla Filiculoides. Laboratory studies have shown that varying concentrations of free metal ions in solution determine efficiency of metal uptake and that metal toxicity can also be detrimental to plant life and efficiency of metal recovery from solution. Many questions however, remain unanswered with regard to the application of a biological treatment for effluent discharge. This thesis includes the determination of metal speciation combined with the study of bioaccumulation of metals in plants and their effects from test- work utilising effluent generated from a Precious Metals Refinery (PMR). Plant species are known to differ widely in their tolerance to metals, however despite an abundant knowledge on molecular, biochemical and physiological effects of metals to plants, only a few general principles have been proposed to guide the prediction of tolerance differences. The properties of protective cellular responses as well as of the molecular target sites are important components in determining the intrinsic tolerance of a particular species to a metal. The role of the whole assembly of cellular ligands in buffering metal ions within the cells will be evaluated. Standard preparation methods combined with use of Inductively Coupled Plasma Emission Spectrophotometer (1CP) used for analytical analysis will be included to reflect analytical data in providing evidence to support a conclusion. The outcome of the test work utilising the aquatic plant Azoila has proven that it can be used as a process step to re-mediate effluent generated from Precious Metal Refining operations. This process offers an alternative to the classical chemical methods widely used in the Precious Metals Refining industry proving economically viable and ensuring environmental sustainability in comparison to the current known methods of effluent treatment. , Thesis (MSc) -- Faculty of Science, Biochemistry, Microbiology and Biotechnology, 2003

- Description: This study analyses the risk-return profiles of securities and constructed portfolio of the South African and Kenya’s stock markets. The analysis is done with cognisance of the dynamism that characterizes contemporary financial markets especially in the face of globalisation. To this end the study inter alia, considers the impact of the technological, information and telecommunications revolution particularly with regard to trading, delivery and settlement period. It also considers the factors that influence the business environment in each of the two markets and how these affect their risk return profiles. Key among the findings of the study are that, only a few sectors and securities in both the South African and Kenyan markets (S % and less than 1 % respectively) exhibited very high risk-return profiles while most of the rest (32 % and 40 % respectively) recorded low risk-return profiles. Overall, the business environment in South Africa is evidently better when compared to that of Kenya. Consequently, each country’s business environment may be used to explain the high/low risk return profiles. , Thesis (MA) -- Faculty of Commerce, Economics and Economic History, 2003

- Description: The two Late Quaternary, diamondiferous pocket beach deposits studied here are situated along a 10 km stretch of the storm-dominated, Atlantic coastline of the Sperrgebiet, south-western Namibia. The pocket beaches are approximately 130 km north of the Orange River mouth, which is widely accepted as a long-lived point source for diamonds sourced from the interior of southern Africa. A total of fourteen pocket beach deposits were recently evaluated in this area, but only two of these, namely Site 2 (to the south) and Site 3 (to the north), are considered here. The main diamondbearing horizons are beach gravels, which occur within, and form part of, the pocket beach sequences. The beach gravels are mostly blanketed by sand overburden, meaning that exposures available for study were limited, and much reliance was placed on borehole logging and observations of evaluation sample tailings. The main aims are to unravel the depositional history of the pocket beach sequences, identify the controls on diamond mineralisation in the beach gravels, and critically examine two different methods of estimating average diamond size for the deposits. In pursuit of these aims, sedimentological characteristics of the unconsolidated pocket beach deposits were recorded using small diameter drill holes, hydraulic grab bulk samples, trench exposures and surface outcrops. The surface geology, geomorphology and modern wave patterns were mapped using high-resolution, Airborne Laser Survey imagery coupled with extensive field checking. Three-dimensional geological modeling software was used to gain insight into the subsurface morphology of the deposits. Fossil shell samples were used to aid interpretation of ancient depositional environments and to date parts of the pocket beach sequences. Variations in diamond concentration and the size of diamonds were recorded using bulk samples, some of which were taken from a trench, but most of which were excavated using a hydraulic grab tool called the GB50. Finally, by using diamond size data from Site 3, sample data from diamondiferous beach gravels to the south of the study area and sample campaign simulations, two alternative methods of evaluating average diamond size in marine gravel deposits were appraised.The pocket beach sequences occur within north-south trending valleys of a major deflation basin and are separated from one another by rocky headlands. The ridge-and-valley topography of the deflation basin has resulted from differential erosion of Late Proterozoic basement rock units, alternating layers of which differ greatly in their resistance to the long-lived, local denudationalprocesses. On the basis of the stratigraphic information collected from the unconsolidated pocket beach valley fills, interpreted within the context of global, Late Pleistocene sea level records, the following depositional history is deduced : a) Deposition of sheetflood gravels by ephemeral streams, activated during a regressive phase. b) Transgression, culminating in the deposition of a gravel beach, representing a sea level highstand of +4 metres above mean sea level (mamsl) at between 120 000 and 130 000 BP. c)A regressive phase, resulting in deflation of former valley fills to the bedrock valley floor and accompanied by re-activation of ephemeral stream activity to form sheetflood deposits; this represents a protracted period of subaerial exposure of the +4 m gravel beach deposit. d) Deposition of a great volume of sediment in the valleys during the latter stages of the transgression from the Last Glacial Maximum (LGM). The sequence generated during this phase, which started at ca. 9 000 BP, contains : i) pan/coastal sabkha sediments, ii) shallow, sheltered bay sediments, iii) back-barrier lagoonal sediments, iv) a gravel beach deposit representing a sea level stillstand at -5 mamsl, laid down between 7 600 and 5 600 BP, v) another gravel beach deposit representing the well-known Middle Holocene sea level highstand at +2 to +3 mamsl, laid down at ca. 5 000 BP, and which terminated the transgression from the LGM. e) A minor regression to the current sea level, accompanied by progradation of the shoreline to its current position. This progradational marine unit consists almost entirely of sand and grit, reflecting the lack of gravel supply to this part of the coastline in the most recent past. f) Deposition of modern coastal dunes, which cap the pocket beach sequence and are the youngest sediments in the study area. Using trench and hydraulic grab evaluation sample results, in combination with analysis of wave patterns and field observations, the following local controls on the density distribution (ie. concentration) and size distribution of diamonds in the gravel beach deposits (+4, -5 and +2 to +3 mamsl stands) are recognised: a) Gravel beach depositional processes, which are responsible for clast sorting on the beach, have influenced the density and size distribution of diamonds. The infill zone, or beach toe, favours maximum diamond concentration while diamond size decreases from the imbricate zone (intertidal) to the infill zone (subtidal). b) Wave energy is identified as the dominant local control on diamond size distribution, but has also influenced diamond concentration to a limited degree. Larger diamonds are intimately associated with coarser beach gravels, both of which are a reflection of increased wave energy. Higher concentrations of diamonds are sometimes associated with zones of coarser gravel and therefore greater wave energy. c) The time of deposition of the host gravel beach is seen to be the dominant controlling factor with respect to diamond concentration. This is seen as evidence of significant temporal variation in the availability of diamonds in the littoral evironment. A significant reduction (20%) in average diamond size from Site 2 to Site 3, over a distance of only 6 km, is evident. The following were identified as reasons for this reduction in diamond size : a) Longshore sorting processes, of which the long-lived northerly littoral drift is a key part, are known to have played a role in the diminution of diamond size northwards from the Orange River mouth point source. However, it is believed that this can only partly account for the observed 20% reduction in diamond size. b) Input of sediment and smaller diamonds at Site 3, reworked out of an older, Eocene-aged marine succession in the hinterland, is recognised as a possible additional reason for the large reduction in diamond size from Site 2 to Site 3. It is also speculated that the large size of the pocket beach at Site 3, relative to Site 2, may have resulted in lower average wave energy at Site 3, with consequent reduced average diamond size. Diamond size in the beach gravels of Site 3, as well as in beach gravels elsewhere in the Sperrgebiet, is seen to be lognormally-distributed within geologically homogeneous zones. In theory, lognormal mean estimators represent the best method of estimating average diamond size in such cases, whereas the arithmetic mean estimator has the tendency to overestimate when large outlier values occur. Lognormal mean estimators have the added benefit of providing for the calculation of confidence limits, which are becoming increasingly more important as financial lending institutions insist on better quantification of the risk involved in resource estimates. Sample campaign simulations demonstrate, for the kinds of diamond size-frequency distributions typical of beach gravel deposits at Site 3, that there is no significant improvement in the accuracy of average diamond size estimates when lognormal mean estimators are used instead of the arithmetic mean estimator. This is because the variance (a ) of the diamond populations is low, and large outlier values are extremely unlikely to occur. However, simulation of a diamond population with high variance, drawn from a sample of beach gravels near the Orange River mouth, shows that lognormal estimators produce significantly more accurate results when a is large. Since individual diamond weights were not recorded during evaluation sampling of Site 3, numerical solution of lognormal estimators is not possible, and these would need to be solved using a less accurate graphical method. It is therefore recommended that individual diamond weights are recorded in future sampling campaigns, allowing for the use of lognormal mean estimators, and the calculation of confidence limits for average diamond size estimates. , Thesis (MSc) -- Science, Geology, 2004

- Description: This thesis investigates the impacts of sudden, unplanned, and violent displacement on farm workers such as Frank Juwawo during Zimbabwe’s recent Fast Track Land Reform Programme. It seeks to illustrate how the members of a complex community were differentially impacted by displacement and displayed differing abilities to mitigate the resulting social and economic impoverishment. In order to illuminate this particular displacement scenario, this thesis uses theoretical and analytical tools developed in the field of displacement studies, adapting them to suit the kind of displacement experienced by Zimbabwean farm workers. , Thesis (MA) -- Faculty of Humanities, Anthropology, 2006

- Description: The antibacterial potency of the extracts of the seed of Garcinia kola (bitter kola) was investigated in this study against a panel of referenced, environmental and clinical bacterial strains. The killing rates of the active extract as well as their potential for combination antibacterial therapy with standard antibiotics were also elucidated using standard procedures. The aqueous and acetone extracts of the seed were screened for activity against 27 bacterial isolates. The aqueous extract exhibited activity mainly against Gram positive organisms with Minimum inhibitory concentration (MIC) values ranging from 5 mgml-1 – 20 mgml-1, while the acetone extract showed activity against both Gram negative and Gram positive organisms with MIC values ranging from 10 mgml-1 - 0.156 mgml-1. The acetone extract also showed rapid bactericidal activity against Staphylococcus aureus ATCC 6538 with a 3.097 Log10 reduction in counts within 4 hours at 0.3125 mgml-1 and a 1.582 Log10 reduction against Proteus vulgaris CSIR 0030 at 5 mgml-1 after 1 hour. In addition, the aqueous, methanol and acetone extracts of the seeds also exhibited activity against four clinical strains of Staphylococcus isolated from wound sepsis specimens. The MIC values for the aqueous extract were 10 mgml-1 for all the isolates while the acetone and methanol extracts had lower values ranging from 0.3125 - 0.625 mgml-1. The acetone extract was strongly bactericidal against Staphylococcus aureus OKOH3 resulting in a 2.70 Log10 reduction in counts at 1.25 mgml-1 within 4 hours of exposure and a complete elimination of the organism after 8 hours. The bactericidal activity of the same extract against Staphylococcus aureus OKOH1 was weak, achieving only a 2.92 Log10 reduction in counts at 1.25 mgml-1 (4× MIC) in 24 hours. In the test for interactions between the acetone extract of the seeds and antibiotics, synergistic interactions were observed largely against Gram positive organisms using the FIC indices, (indices of 0.52 - 0.875) with combinations against Gram negatives yielding largely antagonistic interactions (indices of 2.0 to 5.0). Synergy (≥ 1000 times or ≥ 3 Log10 potentiation of the bactericidal activity) against both Gram negative and Gram positive organisms was detected by time kill assays mainly involving the antibiotics tetracycline, chloramphenicol, amoxycillin and penicillin G. Combinations involving erythromycin and ciprofloxacin consistently gave antagonistic or indifferent interactions. We conclude that the acetone extract of Garcinia kola seeds possess strong bactericidal activities against both Gram positive and Gram negative organisms and can be therapeutically useful in the treatment of bacterial infections including the problematic staphylococcal wound infections. In addition, the acetone extract can be a potential source of broad spectrum resistance modifying compounds that can potentially improve the performance of antibiotics in the treatment of drug resistant infections. , Thesis (MSc)-- Microbiology, University of Fort Hare, 2007

- Description: Whitacre's music is primarily diatonic with subtle modulations, where the new key is always preserved diatonicaliy as well. I refer to this style as expanded diatonicism. Examples in my work of expanded diatonicism within this portfolio are to be found in navem ad somnium, Wynken, Blynken and Nod, as well as Hymn for Brass. My applications of expanded diatonic practices within each of these works are discussed in a separate appendix within the body of this portfolio. That these works are vocal or have a vocal inspiration (Hymn for Brass) reveals the extent of my initial reaction to Whitacre's music during a choral rehearsal. Furthermore, in my vocal compositions especially I chose texts which frequently gravitate towards ideas related to water, the ocean and ships. Whilst water has a soothing and inspiring influence upon me, presumably evidenced in my expanded diatonicism, it also represents my journey and investigation into the sound work of Whitacre in particular. It may be noticed that many of my works in this portfolio have religious orientated themes. I am a Christian, and belong to a Berean 2 Congregational Church. Whilst I am not Catholic or Anglican, I nonetheless have made use of texts from the liturgy of these denominations, as they emphasise the basis of my Christian faith. Why I chose Hymn for Brass as a title could possibly be construed as a religious reference, however it was named after the piece was written, and had no theological connotations in its inception save for the hymnody style of the orchestration. Providence and The Eventide both have a Christian philosophical foundation which is explored in depth in the accompanying appendix. The latter work explores an extension of my expanded diatonic style through incorporating aspects of chromaticism. The rationale for this is dealt with in my discussion of this work. This portfolio represents an overview of my compositional activities to date and displays my growing confidence with the technical aspects of composition as well as my yearning for experimentation with new ideas and manners of expression. , Thesis (MMus) -- Faculty of Humanities, Music and Musicology, 2007

- Description: The conventional definition of sustainable development as proposed by the Brundtland Report (United Nations, 1987), involving the integration of economic, social and environmental components, is widely accepted. Presumed benefits of these current framework applications tend to perpetuate a business as usual status, with no real sustainable development occurring. The growing debate surrounding this topic makes the case for relevant and contextual inputs to be included into sustainable development objectives. A case study, of Gold Fields and Living Gold, attempts to create a deeper understanding of the components of this debate, and begins to contextualise sustainable development principles, goals and their outcomes. This is carried out though an enquiry of the use of cultural development as a fourth sustainable development category. The case study includes the opinions of a directly affected local community entity (Living Gold) in order to observe the difference between the two organisations (Gold Fields and Living Gold). During the study, the focus began to move away from purely unabated growth impacts and looked to the creation and fostering of resilience and flexibility by the use of adaptive management. In breeding states of resilience, it was recognised that cultural impacts played an important role in ensuring long term systemic resilience. The case study involved assessing the feedback and responses of strategically selected individuals at both organisations, with Gold Fields representing a more western centric entity and Living Gold a formal representation of a traditional/ indigenous community. Similarities and differences were assessed in order to understand how current sustainable development criteria might differ between organisations that have different end objectives in mind, yet are dependent on each other. The findings resulted in a perspective of how culture could be used to describe the qualities of a local community, and how to begin aligning development goals with affected communities. The result was the development of the Integrated Resilience Sustainability Method and the consequent development of the Balanced Bottom Line Framework, which seeks to promote sustainable development along the lines of economic, social, environmental and cultural development. , Thesis (MBA) -- Faculty of Commerce, Rhodes Investec Business School, 2007

- Description: Access to global information is inarguably one of the key ways of bringing development to any community. In developing worlds, many rural schools lie outside both the Internet Service Provider’s (ISP) cable network and the national utility grid. Rapid developments in information and communication technology (ICT) continue to widen the digital divide between urban and rural schools. In South Africa, although these rural areas are outside the ISP’s cable network, they enjoy excellent mobile (cellular) communications network coverage. Fortunately, leading mobile operators in the country (MTN and Vodacom) have incorporated mobile data packet services into their cellular communication networks since 2002. A stand-alone photovoltaic (PV) system for powering ICT equipment in off grid rural schools was designed and installed; and its performance monitored. Performance of the system was considered in two categories, which are; cost and service performance. In cost performance, return on investment (ROI) and payback period (PB) are the two critical considerations. The PV system designed in this study gave an impressive ROI and PB of 286percent and 5 years, respectively. In order to monitor and evaluate the service performance a data acquisition system (DAS) was designed and installed. Besides proving the potential of PV in powering ICT equipment, results from the DAS also suggested a more efficient way of employing PV as a power source for powering equipment that is based on Switched-Mode Power Supply Units. Concurrent and continuous change in irradiance and temperature result in a four-segment pattern of rising and falling module efficiency throughout the day. Generally, modules produce more energy on cooler sunny days than hotter sunny days. Infrared (IR) Thermography was also used as part of both indoor and outdoor module tests. During indoor tests at pre-deployment stage, IR Thermography showed development of hot spots in mismatched cells of reverse-biased modules. On the outdoors, IR Thermography reiterated the effect of bird droppings on module surfaces by showing hot spots forming on areas covered by the droppings. For internet connectivity, a customized Mobile Internet Device (MIDevice) was designed, built and tested. The device allows remote computer systems to be connected to the Internet via the already existing mobile communication network k using General Packet Radio Services (GPRS). An entire rural school local area network (LAN) can be connected to the Internet via a single MIDevice. An experimental setup was designed in order to monitor and evaluate performance of GPRS in specific and mobile Internet solutions in general. Results obtained proved that GPRS can indeed be a solution for remote Internet connectivity in rural schools. In order to improve performance of GPRS or mobile Internet connections, caching, pop-up blocking and proxy filtering are necessary. , Thesis (MSc) -- Faculty of Science and Agriculture, 2007

- Description: Remarkably little research has been done about the potential of ethical models for violent conflict resolution in the African context. I will argue here that ethical models such as Utilitarianism, Deontologism, Virtue ethics, and African ethics can exert influence to help resolve conflict situations peacefully for the sake of African civilians generally and the DRC civilians in particular. This influence firstly becomes visible in the fact that ethical models can guide conflict resolution attempts to bring about conditions of peace, justice and freedom among African civilians in whichever nations state they find themselves. Secondly, ethical models can be established in the resolution of conflict for a lasting peace in the African context, and lastly, ethical models can be proposed as a guideline for all African leaders to lead their countries in peace. The conclusion I draw is that a normative framework of ethical models can be applied in conflict resolution in the African context. This framework draws on all four models, but leans toward deontology because of its strictness or rigour of universal rules or principles in any situation. , Thesis (MA) -- Faculty of Social Sciences and Humanities, 2008

- Description: The purpose of this study was to look at how a foreign aid dependent economy is vulnerable to external manipulations. This study came up with the conclusion that foreign capital dependence is detrimental to long-term social, economic, and sustainable development of developing countries. The study also noted how foreign aid is used as a foreign policy instrument by western countries to influence the behaviour of the developing countries. The study noted that Zimbabwe is an aid dependent country hence its vulnerability to external manipulation. This has been demonstrated by capital flight from Zimbabwe since 1997. Multilateral Financial Institutions, the European Union, United States of America and other bilateral donors withdrew their financial support to the country due to policy disagreements with the Zimbabwean government. This incidence of donors withdrawing their financial support to Zimbabwe raises fundamental questions as to whether the African state is autonomous or is it possible for the African state to delink itself from the current global international market and at what costs? What has come out very clearly from this study is that a dependent state has no autonomy to decide on its domestic and foreign policies without considering the interests of its donors, and hence its vulnerability to external manipulations. , Thesis (MSoc) -- Faculty of Management and Commerce, 2008

- Description: In many service industries, the source of a company’s value has shifted from capital to knowledge and ideas, the quality of which is dependent on its employees (Wooldridge, 2006). In fact, human resources can be considered part of factor conditions which can positively impact on a firm’s competitive context. This impact can ultimately translate into improved financial results (Porter and Kramer, 2002). There is therefore a growing interest in ways to attract and retain talent. According to the managers of many big companies, well communicated corporate responsibility practices can improve staff attraction as well as retention rates by improving morale (CSRwire, 2002). To explore this, a small, creative company in Johannesburg which engages in charity work was selected as a case study, with the goal being to understand whether their culture of good deeds has a positive impact on staff wellbeing. While the owner of the company actively attempts to make the company an enjoyable place to work at, he appears to have initiated the philanthropic activities in a true spirit of giving, rather than with the motive of engaging staff in order to make more money. Nevertheless, the researcher’s investigative stance is that of an enlightened egoist, and the study focuses on the business case of giving being beneficial to the giver (ultimately the company) in the long term, as well as to the recipient. While the danger of suggesting that philanthropy could be instrumentalised is acknowledged (Morton, 2004), the investigation explores the possibility because such evidence could persuade other companies to become more socially concerned. Through a qualitative approach involving interviews, observation and analysis of video footage, it becomes apparent that there is clearly value for the staff in the charity work they do. Unfortunately the multiple initiatives undertaken to keep staff morale high at the company make it impossible to establish a clear link between the philanthropy and overall wellbeing, but as the study was conducted in the phenomenological paradigm the main concern was with understanding the experience of participants. However, an unexpected finding was that the employees derive great satisfaction from using their professional skills for charity work rather than just donating money to the charity. They feel that their skills uniquely position them to make significant changes to the lives of others, which gives them a sense of pride and achievement that they don’t necessarily experience in their ordinary activities at work. On the basis of this, it is recommended that companies look to involve staff with projects that require their specific expertise when evaluating philanthropic initiatives. , Thesis (MBA) -- Faculty of Commerce, Rhodes Investec Business School, 2008

- Description: The new political dispensation in South Africa requires that the municipal authorities should involve citizens in policy implementation. In this mini-dissertation, a study is undertaken to investigate the effectiveness of the citizen participation in policy implementation at the King Sabata Dalindyebo municipality. The study emanates from the assumption that citizens are not effectively involved in municipal matters. The main objectives of the study are provide a theoretical framework for policy implementation by describing and explaining its nature and place in Public Administration; provide a constitutional framework for citizen participation in South Africa; evaluate the role of citizens in policy implementation in the King Sabata Dalindyebo municipality; evaluate the interaction between citizens, the councillors and the chief officials in the above municipal authority; and where possible, include recommendations for the improvement of citizen participation in policy implementation in the above municipal authority. The study is envisaged as providing possible solution to the ineffective participation of citizens in municipal matters. The study presents an overview of the legislative framework and the role citizens can play. This is followed by the theoretical framework of the policy implementation within the municipal policy process. Based on the theoretical framework presented, an analysis is then made to prove whether citizens do participate in municipal matters in King Sabata Dalindyebo. It is envisaged that this study will promote the involvement of citizens in municipal matters in King Sabata Dalindyebo municipality. Finally, the study ends by providing recommendations to the problem of ineffective citizen participation in King Sabata Dalindyebo municipality. , Thesis (MPA) -- Faculty of Management and Commerce, 2008

- Description: The research report is submitted to the School of Public Management and Development, University of Fort Hare as part of Masters in Public Administration requirements. The Provincial Growth and Development Plan 2004 2014 has identified agriculture as a critical pillar strategy of poverty reduction and growth in the Eastern Cape Province. The main aim of the study was to assess the viability of the agrarian transformation initiatives in the Eastern Cape. The study therefore was measuring the progress made by the agrarian transformation initiatives in selected areas versus the following variables food security, household community growth, participation and community involvement, and production support. In the attempt to achieve the main objectives, the study focused on the political economy of the rural as the policy context. The literature was an in-depth engagement with body of knowledge on agrarian transformations, with particular interest in governance participation and the impacts of agrarian initiatives in some countries. The product of literature analysis is the hypothetical model, termed the democratised rural agrarian transformation that should shape the policy implementation of agrarian reform. The study also undertook a field work that was guided by research methodology protocols from social science. The study thus collected primary data from 54 farmers participants drawn from 4 local municipalities within Chris Hani and Amathole District Municipalities. The findings of the study showed that there is still a challenge on the potential of rural agriculture to stimulate the improvement of food security status, and rural incomes. This reality is due to various factors such as poor farmer participation, weakness in coordination of the projects, limited access to extension services as a matter of capacity building. The study makes recommendations which are outlined a building local linkages integration with Local Economic Development initiatives and improvement of agrarian social infrastructure dynamic extension services, and political interventions. Conclusively there is need for an intergovernmental approach to the redress of the agrarian question in rural Eastern Cape. , Thesis (MPA) -- Faculty of Management and Commerce, 2008

- Description: The intention of this study was to assess the implementation of performance management system at the Mnquma local municipality. The municipality of Mnquma has in the past been plagued by service delivery challenges and thus the study sought to ascertain whether the challenges could be attributed to the failures of the performance management system within the municipality. It became apparent from the literature review that for any local municipality to play a meaningful role in ensuring that South Africa achieves the goal of becoming a developmental state, capable of confronting service delivery challenges, there needs to be a proper implementation of the performance management system. The study was also aimed at identifying the factors that support or hinder the implementation of the performance management system within the Mnquma local municipality. In order to achieve this objective, scheduled interviews were conducted with various respondents in the municipality. The respondents included the councilors from the four political parties comprising the municipality council, municipal manager and the rest of the Section 57 managers. The key findings that emerged from the data collected, was that the implementation of the performance management system has not been successful. It is also became apparent that there are brewing political tensions that are likely to affect the political stability of the municipality. In addition, it was also evident that there was a minimal or lack of involvement of the local communities in the municipal affairs such as the development of the Municipal Key Performance Indicators. It would therefore be critical important for the management of the Mnquma local municipality to take into account the results of this study and its recommendations so as to ensure that there is a proper implementation of the performance management system within the municipality. , Thesis (MPA) -- Faculty of Management and Commerce, 2008
