"Organisation development is a planned, systematic process in which applied behavioral science principles and practices are introduced into ongoing organisations toward the goal of increasing individual and organisational effectiveness. " [French and Bell] This study describes and analyses the implementation of Organisation Development (OD) to an Anglican Church theological seminary, The College of the Transfiguration (Cott), in the Anglican Church of the Province of Southern Africa (ACSA). The origins of OD are business related, emerging in the late 1950s and early 1960s. Over the years, and recently in South Africa, OD has been applied in educational change initiatives. Unlike more traditional change strategies, OD promotes collaboration in organisational change processes through the inclusive participation of all stakeholders. This study is unique in the sense that OD is applied to an Anglican Church theological institution in Southern Africa. The goal of theological institutions, particularly Cot!, is to "form, inform and transform" (Cot! Prospectus, 2011) those who feel called to ordained ministry. Personal experience in this practice has confirmed that organisational emphasis is placed more on product than process; on results rather than the leadership and management of the organisation. This study was an attempt to introduce a process of planned change to such an organisational context. OD was introduced to The College of the Transfiguration in the form of action research using the Survey Data Feedback (SDF) strategy. Data gathered was interpreted and analysed, followed by action planning and implementation of agreed plans. The process had a positive impact on both stakeholders and the organisation despite the challenges associated with the unpredictable world of organisations. Ultimately, I propose tentative recommendations which could help Cott and other educational institutions to achieve long-term improvement in organisational leadership and management.

The thesis traces Southern African security dimensions from the Cold War and the period of apartheid in South Africa to the post-apartheid era. It makes an attempt to investigate the prospects of Southern Africa becoming a security community and the processes and practices underlying these efforts. Using the constructivist theory approach to international relations, the thesis argues that the preoccupation with principles of sovereignty and non-interference, a lack of political will and the absence of common values that could help SADC institute binding rules and decision-making are the main blocks that prevent the region from asserting itself as a security community. All these militate against the idea of mutual accountability among SADC member states and have a negative impact on the institutional and functional capacity of SADC. This also prevents SADC from dealing with the emerging non-military human security threats in the region. In consideration of this, the thesis argues that the idea of security community building in Southern Africa remains not only a regional issue, but also requires the involvement of extra-regional actors.

The nyala on Buffelsdrift Private Game Reserve were found to be mainly browsers and made little use of grass during the study period. Browse contributed 87.8 percent to the annual diet, while grass contributed 12.2 percent. Only six species formed > 5 percent of the annual diet. Of these six only three species formed > 10 percent. They are the shrubs Acacia karroo, Pappea capensis and Grewia robusta. These were followed by the shrub Portulacaria afra, the dwarf shrub Zygophyllum lichtensteinianum and the grass Cynodon dactylon all contributing between 5 - 10 percent. There were definite seasonal dietary shifts with preference to different plant species. The shift takes place between the wet seasons (winter and spring) and the dry season (summer). Herbaceous species such as Cynodon dactylon and Erharta calycina were favoured in the winter/wet season. Shrubs such as P. capensis, P. afra and dwarf shrubs such as Limeum aethiopicum and Z. lichtensteinianum were favoured during the spring/wet and summer/dry seasons. Nyala habitat use in BPGR differed significantly from expected use when taking the relative area of habitats into consideration. However nyala did not display signififcantly different habitat preferences between seasons. Male and female nyala displayed differences in foraging behaviour at the plant form, plant species and habitat scale. Males preferred a greater proportion of shrubs and females a greater proportion of dwarf shrubs. Males preferred the shrubs Pappea capensis and Portulacaria afra the most and females preferred the dwarf shrubs Limeum aethiopicum and Zygophyllum lichtensteinianum the most. Plant species site availability varied significantly between the sexes, indicating that males and females selected different feeding paths. The difference in their feeding strategy appears to be related to the selection of plants that best satisfy the nutrient requirements of each sex. These findings are in agreement with the results from earlier studies on nyala sexual dimorphism. At the habitat scale females selected more for open dwarf shrubland and males more for densely vegetated habitats. This appears to be as a result of males attempting to maximize their foraging opportunities by selecting areas that offer food in greater quantities. Nyala in BPGR appear to co-exist with kudu and eland through spatial resource partitioning. This is suggested to be due to the influence of body size-gut size relationships on forage selectivity.

MENVSC (Climatology) / Department of Geography and Geo-Information Sciences / Subtropical anticyclones locate and modulate weather and climate over subtropical belts for both the Northern and Southern Hemispheres. This study investigates the spatio-temporal variability of the Mascarene High over the South Indian Ocean on (anomalous) weather and climate over southern Africa at intraseasonal, seasonal, interannual, multidecadal and event time-scales. The Mascarene High is located 25-35°S, 40-110°E, playing a vital role in day-to-day weather and climate patterns conditions over southern Africa. Spatio-temporal characteristics of the Mascarene High investigated in this study span the period 1985-2014 and 2071-2100, using NCEP-NCAR reanalysis datasets for present-day climate observations and the Conformal-Cubic Atmospheric Model (CCAM) for future projections. The Mascarene High is analysed using mean sea level pressure (MSLP) extracted from ECMWF ERA-interim monthly reanalysis data. The Mascarene High is also subjected to Principal Components Analysis, depicting eastern displacements of the weather system to be dominant for weather and climate fluctuations over southern Africa. The Mascarene High migrates south (north) during austral summer (winter) and is centred over the eastern Indian Ocean in summer in connection with the Indian Ocean Subtropical Dipole. Event scale analysis is also employed for investigating Mascarene High blocking and induced anomalous weather. Mascarene High blocking leads to anomalous rainfall events over southern Africa associated with tropical cyclones, cut-off lows and cloud bands. There is also a vital geographical variability of the Mascarene High development, distribution and movement in the South Indian Ocean at the different time-scales. Projections of the Mascarene High indicate a shift in mean location as a result of future expansion and intensification. This projected expansion and intensification is expected to shift tropical cyclone trajectories equatorward, with the baroclinic structure of cold fronts expected to shift poleward affecting changes in the weather and climate of southern Africa. This finding is important as it projects changes in weather and climate conditions over southern Africa in a changing climate due to increased greenhouse gas emissions.

This study covers an investigation into project management best practices in Southern Africa. The purpose of the research was to determine which of the current accepted project management tools and techniques are seen as critical in the region. It also focuses on determining any external or internal factors that hamper effective development of project management in the Southern African region. The study further tries to determine whether there are any noticeable differences between accepted project management practices in the developed world and practices used in the region. The study was conducted using a survey with a mix of open and scaled questions and was sent out to a number of companies selected because they employ established project managers. A total number of 400 questionnaires were sent out and 42 completed questionnaires were received from respondents. The study found that there are no significant differences between the techniques used for project management in Southern Africa and techniques used in the rest of the world. There are, however, several factors influencing project management development in the region that are unique to the region including a severe shortage of skilled people and infrastructure problems. There is also a lack of knowledge about project management practices amongst respondents and amongst other members of their organizations including senior management. This lack of knowledge combined with the shortage of skilled people can result in serious problems with the execution and management of projects in the Southern African region. / Graduate School of Business Leadership / MBL

Thunderstorms, due to their high frequency of occurrence over southern Africa, and their major contribution to summer rainfall are the primary focus of very short range forecasting and nowcasting efforts in South Africa. With a limited number of surface and upper-air observations and the limited availability of numerical model output most southern African countries are heavily reliant on satellite technology. In developing tools for the first twelve forecast hours the South African Weather Service has to address both the national and regional needs. Thus, the blending of techniques in an optimal manner is essential. This study initially describes how the Global Instability Index product derived from the European Meteosat Second Generation Satellite was adapted for South African circumstances using a different numerical model to provide background information – creating the Regional Instability Indices (RII). The focus of the study is the development of a new convection indicator, called the Combined Instability Index (CII), which calculates the probability of convection from satellite derived instability indices and moisture, as well as height above sea level early in the morning when the sky is relatively cloud free. Early morning CII values were evaluated statistically against the occurrence of lightning over South Africa, where a lightning network is available, as well as against satellite derived precipitation over southern Africa, later in the same day. It is shown that the CII not only performs well, but also outperforms the individual RII when compared to the occurrence of lightning. The CII will be beneficial to operational forecasters to focus their attention on the area which is most favourable for the development of convection later in the day. / Environmental Sciences / Ph.

This thesis examines regional integration in Southern Africa and the evolution of SADC. Regional developments are evaluated with the yardsticks of integration theory, against the background of international regionalisation, and in terms of the region's practical record, its rhetoric and future agenda. The extent to which economic integration is progressing, is determined, after which the thesis focuses on political integration within SADC - both de Jure and de facto. Finally, developments within the region are evaluated in light of normative prerequisites for increased political integration. The thesis finds that the integration process in SADC does not fit into traditional integration theory, and concludes that successful economic integration in the region is not necessarily a prerequisite to political integration, but would facilitate it. The research finally concludes that there is evidence of embryonic political integration within SADC, which will wane or grow depending primarily on the political will of its constituents / Political Science / M.A. (Politics)

Churches are confronted with the reality of younger, mobile generations challenging existing understandings of church and witness. They seem to live according to a different (postcolonial) script. This study probes the question as to how these churches are to understand and respond meaningfully, but also missiologically, to these transformations. Coming as a missiologist from a particular ecclesiological, theological, cultural background, I had two rationales for this study, namely to review the current theories we have about church and mission, i.e., missiological ecclesiology, and in order to do this, we need to craft a sensitive and creative dialogue, in the form of a missiological methodology with younger people. I address these rationales, guided by a research question: How can I design a creative dialogue with younger generations, to pick up the impulses, in order to discern a Southern African missional ecclesiology. Working with the metaphor of ―remixing‖, this discernment process started off where I engaged my own embeddedness. These were the older ―samples‖ to work with, in order to produce something new and in tune with the sensibilities, the ―soul‖ of newer communities. I then attempt to understand the current social transformations that younger generations are responding to. Through this, I want to design a methodology for a creative dialogue with these youth movements on the basis of an intersubjective epistemology. Using this methodology, I could develop a thick description from the dialogue with the two uniting youth movements. Lastly, I present the engagement (remixing) between these rich new impulses with the old (the existing), in carving out an appropriate missional ecclesiology for the audiences I‘ve been with. Starting with an outdated and colonial gereformeerde missionary ecclesiology, but then also the anti-colonial ecclesiologies and a postmodern (predominantly Western) emerging missionary ecclesiology, I discern a particular postcolonial African ecclesiology, which I call a Southern African missional ecclesiology. Instead of exclusion, I propose remixing church in terms of five dimensions as social network, spiritual home, mobile community, movement in the Holy Spirit and as story. These can serve as a map to guide Southern African congregations in their dialogue with younger generations. / Christian Spirituality, Church History & Missiology / D. Th. (Missiology)

Thesis (MA (Political Science.International Studies))--University of Stellenbosch, 2006. / This study is based on the premise that HIV/AIDS and variable rainfall, in other words, events such as droughts and floods (climate), are likely to be prevalent in Southern Africa for the foreseeable future. Thus, these two factors are likely to accompany future food crises in the region. This study investigates the Southern African Food Crisis in the period 2001-2005, with certain objectives in mind. Firstly, the impact of HIV/AIDS and climate on food security is investigated. Secondly, in light of the findings relating to the first objective, it is investigated what an optimal humanitarian intervention in a food crisis in the Southern African context, characterised by variable rainfall and high prevalence of HIV/AIDS, might entail. Finally, the appropriateness of humanitarian interventions in the Southern African Food Crisis to ameliorate the long-term impacts of HIV/AIDS and climate on the region is considered. The study makes use of an extensive literature review, supplemented by a smaller set of e-mail and semi-structured interviews. Especially with regards to the second and third research objectives, the Consortium for the Southern African Food Security Emergency (C-SAFE) is used as a case study of an intervention in the above stated context. C-SAFE – composed of a consortium of international and local non-governmental organisations - is the largest humanitarian intervention programme that was created with the specific goal of ameliorating the food crisis in the Southern African region. They were primarily active in four countries: Lesotho, Malawi, Zambia and Zimbabwe. The study focuses on C-SAFE operations in these four countries in order to asses the impact of variable rainfall and HIV/Aids and other underlying causes – such as macroeconomic factors and government policy – on food insecurity in Southern Africa and to examine how these factors influence a humanitarian intervention programme such as C-SAFE. The most important findings of this study are that neither HIV/AIDS nor climate is driving food insecurity in Southern Africa. The impact of HIV/AIDS can however be devastating at household level. It is found that both factors, serve as catalysts bringing to the fore the underlying vulnerability of households. The findings of this study further suggest that interventions should provide resilience building to shocks such as drought, indicating a complex set of relief and developmental needs in the region. Furthermore, HIV/AIDS can be seen as a crisis in itself, requiring a comprehensive multisectoral response, however possibly requiring special attention in times of food insecurity. Finally it is argued that livelihoods erosion over time has meant that the work of relief agencies fulfilling their mandate, providing short-term relief to households and communities in need, regardless of the quality of such interventions, are ineffectual in addressing cycles of vulnerability in Southern Africa as inadequacies at national level, most notably a lack of government capacity, remain.
