- Description: This thesis explores the phenomenon of illegal natural resource exploitation in conflict zones and the application of international criminal law, particularly the Rome Statute of the International Criminal Court to combat the roblem. Contemporary African conflicts, such as the Democratic Republic of Congo conflict explored as a case study herein, have become increasingly distinguishable by the tight connection between war and various forms of illegal natural resource exploitation, particularly targeting valuable and precious mineral resources. With their incidence being highest in Africa, wars funded by illegally exploited natural resources have gradually become one of the greatest threats to regional peace and human security on the African continent. The Congo conflict clearly demonstrated the problematic nature and impact of illegal natural resource exploitation and the widespread human, economic and political costs associated with this phenomenon. This thesis is based on the initial assumption that the quest by conflict actors to profit from war through illegal natural resource exploitation activities is at the centre of the commission of serious human rights violations as well as the complexity and longevity of African conflicts. Developments in international criminal law, culminating in the adoption of the Rome Statute and the establishment of the International Criminal Court, have given impetus to the argument that any group of conflict actors should be subjected to the individual criminal responsibility regime of this legal framework. A further underlying assumption of this thesis is therefore that international criminal law can constrain the acts and conduct defined in this thesis as illegal natural resource exploitation activities since they constitute war crimes under the Rome Statute framework. However, despite illustrating the illegal resource exploitation activities of various state and non-state actors, this thesis is confined to an application of the Rome Statute based international criminal liability regime against members of armed rebel groups involved in such acts. In exploring these issues, this work examines international criminal law institutions and the relevance of international criminal justice in addressing particular phenomena prevalent during African armed conflicts. It further provides the stage to assess the potential of international criminal law in safeguarding natural resources for the benefit of African societies perennially exposed to the depredations of natural resource financed warfare. , Microsoft� Office Word 2007 , Adobe Acrobat 9.53 Paper Capture Plug-in

- Description: An ecological reserve study by the Department of Water Affairs on the Great Brak Estuary stated that there was a need to determine how much nitrogen and phosphorus was flowing through the estuary as well as how effective the macroalgae were at removing N and P. The objective of this study was to investigate the physico-chemical characteristics in the estuary and the influence of these on the submerged macrophytes and macroalgae. A nutrient budget for the estuary was developed in order to quantify the contribution of the submerged macrophytes and macroalgae relative to other contributing sources. The Wolwedans Dam located 3 km upstream from the estuary has reduced the amount of freshwater flow to the estuary by as much as 56 percent. The estuary has been allocated 2 x 106 m3 per annum of freshwater (ecological reserve) that is used to breach the mouth once or twice a year in spring or summer. Even though this water has been made available it is not sufficient to flush the estuary. Reduced flushing has led to an accumulation of organic matter and degradation in the water quality. Physico-chemical measurements between September 2010 and July 2012 showed that dissolved oxygen values were generally below 6 mg l-1. The average NH4+ concentration in the estuary was 7 μM and increased with depth to 12 μM at 2 m depths. Concentrations >45 μM were found in February and April 2011 at the 5 m deep hole at 3.4 km upstream. Negative correlations between dissolved oxygen and NH4+ during November 2010, February 2011, April 2011 and July 2011 (r = -0.68; -0.67; -0.63; -0.96) indicated that remineralisation of organic matter had occurred. Soluble reactive phosphorus (SRP) followed a similar trend to the NH4+ and was generally below 1 μM in the water column for most months, and had peaks at 1.0 km and 3.4 km in the bottom water. The abundance of submerged macrophytes and macroalgae below the N2 bridge were mostly influenced by mouth state and river inflow. During the closed phase the dominant macroalga Cladophora glomerata had an area cover ranging from 3000 to 6000 m2 while Zostera capensis and Ruppia cirrhosa covered an area of 2000 to 3500 m2 and 1500 to 2900 m2, respectively. After an artificial breach in February 2011, water drained out of the estuary leaving the alga stranded on the marshes and as the flood tide entered the macroalga was once again redistributed in the lower reaches. The alga utilised the available nutrients in the water column and expanded its area cover from 35000 m2 in February 2011 to 64000 m2 in March 2011. However, after the floods in June 2011, Cladophora glomerata had been washed out of the system while the submerged macrophytes responded positively extending their area cover. By comparing the artificial breach with the natural breach, and the effect on the estuary, an important observation was highlighted. Increasing the current allocated ecological reserve, and using a larger volume of water to breach the mouth artificially, would result in better scouring of sediment and associated organic matter out of the estuary. This would enable better oxygenation of the water column, reduce remineralisation and minimise algal blooms.

- Description: The reason for the existence of any company is to make a profit, which means increasing turnover and keeping costs as low as possible. Optimisation of the Value Chain and Procurement were identified as the two largest contributors when one needs to improve the bottom line of any company. The purpose of this research was to develop an integrated Value Chain and Procurement cost reduction methodology and system specifications for a software solution which captures, tracks and accurately reports the impact of the improvement initiatives. The main research question was structured as follows: What should the specifications of a software solution be that will integrate the cost reduction processes of the Value Chain and of Procurement, in a manner that will ensure maximum sustainable bottom-line savings for companies in the manufacturing or service industries? The objective was to define the key phases in the Value Chain and Procurement cost reduction process and to determine how and where they integrate. It is important to note that according the literature review and the survey, both the Value Chain and Procurement cost reduction processes consist of seven phases. The phases of the Value Chain cost reduction process were: Phase 1: Budget/ABC costing and data analysis; Phase 2: Generate ideas; Phase 3: Evaluate and approve ideas; Phase 4: Implementation planning and approval; Phase 5: Development of project (idea) specific KPI's; Phase 6: Implementation of ideas; Phase 7: Track and report savings. The phases of the Procurement (Strategic Sourcing) cost reduction process were: Phase 1: Team selection/data collection/spend analysis/work plan development Phase 2: Access requirements/internal and external analysis; Phase 3: Develop strategy/shape value proposition; Phase 4: Screen suppliers, issue RFI/P/Q, implementation planning; Phase 5: Conduct commercial event/negotiate/finalise contract; Phase 6: Implement contract; Phase 7: Contract management/track and reporting. The above two cost reduction processes integrate at each phase of the respective processes and should thus be implemented at the same time due to their interdependencies. Based on the findings of the research it was clear that an integrated Value Chain and Procurement cost reduction process alone is not going to solve the cost reduction problems of companies. It is essential for the successful implementation of the integrated cost reduction process to develop skills and knowledgeable resources to implement the integrated cost reduction process, improve collaboration between the Value Chain and Procurement, and to implement a system to track and report performance during implementation. Further research should include how to adapt the current company processes, structures, procedures and systems in order to gain maximum benefit from the implementation of an integrated cost reduction process. The integrated Value Chain and Procurement cost reduction process, supported by a software system, should improve the success of cost reduction projects in companies. It is, however, important to note that the application of the methodology will vary between industries and that service-related industries might put more emphasis on Procurement cost reduction, while the manufacturing industries might place a bigger emphasis on cost reduction in operations. In conclusion, irrespective of the industries, it is evident that this methodology will enhance the cost reduction results previously obtained from similar efforts.

- Description: Shamwari Game Reserve was the first enclosed conservation area in the Eastern Cape Province of South Africa to reintroduce free ranging lions, cheetahs, leopards and wild dogs back into their historic range. At that time (2000 – 2001), little information was available on the ecology and behaviour of these predators in the habitats of the Eastern Cape, and management decisions were based on assumptions and unfounded comparisons with extant populations but from quite different habitats. The aim of this study was therefore to obtain a better understanding of the feeding ecology and space use of the predator guild, and the carrying capacity of Shamwari Game Reserve to enable more informed management decisions. In addition, the reserve is a photographic based tourism venture and understanding both the ecological and financial sustainability of the predator guild was important. The diets of the predators were similar to those reported in other studies; larger predators killed a greater range of prey species than did smaller predators and a small number of prey species made up the majority of the kills. The larger predators had a higher mean kill mass than the smaller species and prey selection was influenced by prey size, prey abundance and prey habitat preference, and risk associated with hunting the species. Diet was flexible and responded to natural and management induced changes in prey abundance. There was a considerable overlap in space use by the lions, cheetahs and leopards with their core areas being centred on and around the Bushmans River. Space use was driven by resource distribution and landscape attributes, and by the presence of other predators of the same or different species. The long term viability of wild dog within the reserve was explored and the results confirmed that there was neither the required space nor the ecological processes and the wild dogs were removed from the reserve. A carrying capacity of the reserve for the predator guild was determined using the Maximum Sustainable Yield method to assess the potential prey species off take and a resultant density of 3.3 to 6.6 lion female equivalent units per 10 000 ha was established. The natural carrying capacity of the reserve with respect to predators will not sustain the tourism objectives and consequently prey supplementation was necessary to maintain predator density at levels high enough to sustain tourism. Under these conditions the large predator guild is still sustainable financially although careful, responsible management is needed to provide ecological sustainability.

- Description: Historically the process of career development was thought of as occurring in adolescence and adulthood; however, the renewed emphasis on lifelong career development has led to a greater focus on the career developmental stage of childhood. The present research focused on the development and trialling of a research-based computerised career exploration tool, Growing-up: Children Building Careers™ (GCBC™) that can be used for early intervention in children‘s career development. The integration of developmental considerations within a career developmental context is of paramount importance, considering that child and career developmental theories share certain basic foundational principles such as the dual recognition of identifiable life stages and the resolution or accomplishment of associated tasks. The focus of the research is to provide access to a research-based tool that can assist learners with developing age appropriate career developmental skills. As the overview of education policy and existing programs will show, there are challenges in providing access to and improving the nature, level, and quality of career development services. Gaps in access to career development learning are particularly evident at the elementary education level. Furthermore it is clear that learners need to be at the centre of a radical rethink of careers services within a lifelong learning framework in order to ensure access to navigational tools throughout a lifetime of work and study transitions. Digital environments, such as the GCBC™, are tools that broaden and extend learning possibilities for children and appropriately designed digital environments can provide a vehicle that can take children further than they might travel unassisted. The research is divided into five phases and includes eight to ten year old children as participants. Phase one focused on the program design and pilot study (ensuring content validity and age-appropriate language use), while phases two to five focused on the fieldwork (i.e., pre –test, program exposure, post-test, and focus group discussions). The researcher made use of a mixed research design that combines both quantitative and qualitative research methods. The total sample consisted of 146 children between the ages of eight to ten years old. The control group had 72 children and the experimental group 74 children with a mean age of 8.74 years (SD = 0.63) for the total sample. The quantitative data collection entailed a pre-and post-test design with learners‘ career development measured with the Childhood Career Development Scale (CCDS) and their career awareness with the Revised Career Awareness Survey (RCAS). Qualitative data was collected in the form of two focus group discussions, which included a small sample of children from the experimental group, as well as insights gained from educators following the GCBC™ fieldwork. The quantitative statistical analysis included descriptive and inferential statistics which allowed the researcher to not only describe the research findings, but to confirm the effectiveness of the GCBC™ as an intentional career development learning program. Furthermore, the responses of the children and educators who participated in or witnessed the facilitation of the GCBC™ provided support for the GCBC™ as a meaningful career learning experience which can be successfully implemented in educational settings.

- Description: In Mozambique, establishment of aquatic weeds has been enhanced through the increased enrichment of water bodies by nutrient runoffs from human and agricultural wastes that lead to an increase in nitrate and phosphate in the water. The aquatic weeds, water hyacinth (Eichhornia crassipes), red water fern ( Azolla microphylla), water lettuce (Pistia stratiotes) and salvinia (Salvinia molesta) were found in most watercourses in Mozambique and are becoming aggressive in some watercourses, especially in the Umbeluzi and Incomati rivers. Farmers and people living along the rivers are aware of the negative impact of the water weeds because the large mats of weeds cause loss of shoreline and navigability along the rivers. Other commonly perceived effects of aquatic invasive plants in Mozambique rivers include: reduced navigable surface area; difficulties for fishermen, which reduces income; increased prevalence of insects and insect-borne disease, and decreased aesthetic value. The methods currently used for the control and management of the aquatic weeds are mechanical and manual control. Both methods are costly, time consuming, and only provide a short-term solution to the problem. The study found that the weevils Neochetina eichhorniae and N. bruchi were effective biological control agents in the study area but their impact is too gradual compared to the aggressive proliferation of water hyacinth. The one year lab-experiment clearly demonstrated that the water lettuce weed had a significant impact on the recruitment of macro-invertebrates to the artificial substrates, and water lettuce contributed to the reduction of oxygen in the water and consequent reduction of macro-invertebrate abundance and diversity. The biodiversity recovered at the same time in the pools containing water lettuce controlled by N. affinis and water lettuce controlled by herbicide, but richness and diversity of macro-invertebrates was higher in the water lettuce controlled by N affinis during the first sampling occasion compared to the water lettuce in pools controlled by herbicide, where macro-invertebrates increased only when DO levels recovered after water lettuce mat decay. The number of taxa recorded in this study is an indication of the significance of macro-invertebrates in an aquatic environment. This therefore emphasizes the need for more research efforts into macrophyte and macro-invertebrate associations in the aquatic system to better understand the implications of habitat modification arising from human activities. It will also enable us to be better equipped with a more appropriate ecological understanding for aquatic resources management.

- Description: In Mozambique, establishment of aquatic weeds has been enhanced through the increased enrichment of water bodies by nutrient runoffs from human and agricultural wastes that lead to an increase in nitrate and phosphate in the water. The aquatic weeds, water hyacinth (Eichhornia crassipes), red water fern ( Azolla microphylla), water lettuce (Pistia stratiotes) and salvinia (Salvinia molesta) were found in most watercourses in Mozambique and are becoming aggressive in some watercourses, especially in the Umbeluzi and Incomati rivers. Farmers and people living along the rivers are aware of the negative impact of the water weeds because the large mats of weeds cause loss of shoreline and navigability along the rivers. Other commonly perceived effects of aquatic invasive plants in Mozambique rivers include: reduced navigable surface area; difficulties for fishermen, which reduces income; increased prevalence of insects and insect-borne disease, and decreased aesthetic value. The methods currently used for the control and management of the aquatic weeds are mechanical and manual control. Both methods are costly, time consuming, and only provide a short-term solution to the problem. The study found that the weevils Neochetina eichhorniae and N. bruchi were effective biological control agents in the study area but their impact is too gradual compared to the aggressive proliferation of water hyacinth. The one year lab-experiment clearly demonstrated that the water lettuce weed had a significant impact on the recruitment of macro-invertebrates to the artificial substrates, and water lettuce contributed to the reduction of oxygen in the water and consequent reduction of macro-invertebrate abundance and diversity.

- Description: Diversity should be included in an organisational culture and be aligned with the corporate strategy. South African institutions face diversity and multiculturalism challenges which affect their operation and strategies. Managers in South Africa regard organisational culture as a very useful tool to manage their diverse workforce. Against this background, the primary objective of this study was to investigate and analyse how workforce diversity and organisational culture impact on strategy implementation at a higher education institution, namely Walter Sisulu University (WSU). The study identified dimensions of diversity and organisational culture and strategy implementation from theoretical models supporting the study. A hypothetical model portraying these factors was constructed, displaying each factor and their relationship with strategy implementation. Furthermore, the relationship between strategy implementation and strategic outcomes was indicated. Given the nature of the problem statement and the research objectives presented in this study, the positivistic research paradigm was adopted. Self-administered questionnaires were distributed to executive and senior management, senior academic and senior support staff at WSU. In total, 266 usable questionnaires were returned. The data obtained from these questionnaires were subjected to both descriptive and inferential statistical analyses. Structural equation modeling (SEM) was used as the key statistical analysis tool. As the hypothetical model did not load onto SEM in total, it was re-specified into four sub-models. Each sub-model was subjected to SEM to test the hypothetical model and to indicate the significance of the relationships hypothesised between the various independent, mediating and dependent variables. Eight statistically significant relationships were identified in the study. The factors identified as having a statistically significant relationship with organisational culture included the following: degree of flexibility, degree of teamwork, task directiveness, degree of formalisation, leadership styles and decision making. In addition, a statistically significant relationship was found between organisational culture and strategy implementation. Furthermore the findings indicated a statistically significant relationship between strategy implementation and strategic outcomes in a higher education institution. There was no statistically significant relationship found between diversity and strategy implementation. This finding is contrary to empirical evidence by various other researchers. The study makes a contribution to multicultural higher education institutions by highlighting the crucial role of organisational culture in effective strategy implementation. It was clear from the results of the study that the nurturing of human capital is critical if higher education institutions wish to successfully aligning culture with strategy implementation. This study provided constructive and very practical guidelines to higher education institutions to ensure effective alignment of culture with strategy implementation and so enhance local and global competitiveness and long term sustainability. University councils throughout South Africa can apply the findings of this study in their respective institutions to support effective strategy execution.

- Description: Most smallholder farmers in South Africa are characterized by poor resources such as land, labour and capital while they play an important role in poverty alleviation especially in poor rural areas. Smallholder farmers are increasingly recognized because of their contribution to household food security. The world markets are increasingly being integrated due to globalization and liberalization. As a result, smallholder farmers are facing increasing market competition, not only in international markets but in local markets as well. However, smallholder farmers often face a number of barriers to accessing these markets arising in part from the tightening of food safety and quality standards requiring compliance with phytosanitary and sanitary standards and growing power of supply chain integration. Furthermore, the viability of these smallholder producers is constrained by institutional obstacles which include lack of access to information, high marketing and transaction costs and low quality and lack of critical volume in the absence of bulking up arrangements, etc. These barriers have contributed to the exclusion of smallholder/small-scale farmers from formal markets. In order to address these obstacles and speed up the pace of agrarian reform many support schemes (farmer support programmes) are now being designed to specifically address market access and value chain issues through unique co-innovation arrangements to improve the farmer’s access to profitable international chains. A number of farmer support programmes (FSP) have been implemented in South Africa to reduce the risk of a lack of capacity and a lack of economic and/or financial experience in smallholder farms. Intervention measures have been instituted to these smallholder farmers to assist them to move out of poverty through agricultural production. The aim of this study was to understand the roles played by farmer support programmes in addressing income and welfare levels and sustainability of smallholder farmers in South Africa. Eighty nine (89) farmers were interviewed for this study and almost half (49%) of them received support from various organizations while 51% of the sampled farmers did not receive any support. The study was designed to compare the two groups between the treated and control group to assess the impact of these programmes.Using a Tobit and Propensity Score Matching technique, potential diffusion effects were eliminated between farmers supported by Farmer Support Programmes and farmers that did not belong to support services. The latter was selected from comparable communities with no agricultural support services. Findings from the Tobit regression and propensity score matching are consistent across the two methods, suggesting that being a member of any agricultural support programme has a significant positive impact on income and welfare of smallholder farmers.Farmer Support Programmes and collective marketing activities such as the collection and sale of members’ products appear to have a significant and positive impact on smallholder welfare of those farmers engaged in them. In the second analysis the study tested the types of arrangements that farmers would adopt to market their produce. From the results it was established that those farmers who were supported by institutional arrangements or FSP had better access to markets than those farmers who operated as individuals. Marginal effects are used to show the degree to which farmers chose a particular marketing channel or institutional arrangement that these farmers take when trying to access better paying markets. Then the final analysis is on factors that determine the extent to which collective action contribute to farmers’ income and market access. A number of variables (age, distance to the market, region the farmers are located) were evaluated using the multinomial regression model. Empirical results suggest that among South African cooperatives, those established in KwaZulu-Natal and partly in the Eastern Cape and upon the voluntary initiative of farmers are more sustainable and have access to better paying markets both locally and internationally than the other areas. The results also show that NGO-supported cooperatives have a longer life span than Government controlled cooperatives.

- Description: The process of trade liberalisation and market-oriented economic reforms was initiated in many developing countries in early 1980s; and it intensified in 1990s. In 1991, Zimbabwe was assisted by the IMF to implement trade-policy reforms under Economic Structural Adjustment Programme (ESAP). After adopting ESAP, the country witnessed soaring balance-of-payment problems, contraction of output, unemployment and the loss of government revenue. A number of factors, which were at play resulted in dismal economic performance under ESAP. These factors still exist, in addition to inter alia weak economic policies, structural rigidities and weak institutions. However, notwithstanding this controversy, the country continuously opened its economy under Common Market for Eastern and Southern Africa (COMESA), Southern Africa Development Community (SADC), World Trade Organisation (WTO), Economic Partnership Agreements (EPAs) and bilateral agreements. It is against this background that this study is undertaken, in order to evaluate the impact of different trade-policy regimes on trade, welfare and revenue in Zimbabwe. This study used two models: World Integrated Trade Solutions/Software for Market Analysis and Restrictions on Trade (WITS/SMART) and Tariff Reform Impact Simulation Tool (TRIST). The WITS/SMART model was used because of its ability in analysing the tariff effect of a single market on disaggregated product lines. The model also has the capability to analyse the effects of trade-policy reforms in the presence of imperfect substitutes. In order to complement the WITS/SMART model, a TRIST model was also used. The use of the TRIST model enabled the study to evaluate the impact of trade reforms on VAT, excise duties, collected and statutory revenue – which the WITS/SMART model had overlooked. Using the WITS/SMART model, the study considered seven trade-liberalisation frameworks for Zimbabwe: full implementation of the SADC free trade agreement (FTA), SADC common external tariff (CET), COMESA CET, COMESA FTA, EPAs, BFTAs and WTO FTA.

The Impact of the common law and legislation on African indigenous laws of marriage in Zimbabwe and South Africa

- Description: The study sought to examine the development of customary law, primarily focusing on the extent to which the true African marriage has been preserved by its incorporation in, and regulation by legislation and the constitutions of Zimbabwe and South Africa. Today, colonial legislation has either been repealed or revised. However, evidence persists suggesting the inclusion of western principles within frameworks governing African marriages such as the Customary Marriages Act and the Recognition of Customary Marriages Act of post-independence Zimbabwe and South Africa respectively. To understand the true purpose of custom, the study initially investigates the classical customary law position drawing deeper insights into the main features of the African marriage. From an African perspective, the research revealed whether legislation satisfactorily dealt with aspects such as registration of customary marriages, determination of minority and capacity to marry, payment of bride wealth, grounds for divorce, proprietary consequences of marriage during and after termination of marriage by death or divorce and women’s rights to communal land tenure and immovable property among others. Apart from legislation it became imperative to determine the role of constitutionalism and human rights law in the regulation and preservation of custom. A comparative study was motivated not only because Zimbabwe and South Africa share a border but also because migration between the two countries in the past decade due to various socio-economic forces has led to inter-marriages and cultural diversity. In addition, historically, both jurisdictions have Roman-Dutch law as the basis for the formation of their legal systems. The methodology remained largely a qualitative type research based on documentary analysis. Several findings emerged among which was the fact that, women in traditional African marriages had property rights contrary to popular belief however they continue to be most disadvantaged when it comes to having real rights in ownership of communal land. The African marriage generally sought to preserve marriage more than its western counterpart, the civil marriage. Legislation was the main vehicle for attaching customary law to western principles of law thus losing its intended purpose. Other findings were that polygamy and widow inheritance are prevalent and continue to face condemnation in today’s society; constitutionalism and international human rights law do not readily find acceptance among traditionalists; bride wealth payments persist among rural and urban folk alike and continue to symbolise a marriage between respective parties and their families; and spouses omit to register customary marriages mainly because bride wealth payments adequately legitimise their unions. Initiation ceremonies persist among some ethnic groups particularly the South African Xhosa who have adhered to circumcision for boys as determining their capacity to marry. The study concludes by making recommendations that could assist in harmonising customary law and common law. These include educational initiatives; advocacy and advice giving; regulation of unregistered customary marriages; improving access to justice; eradication of child marriages; improving the status of rural women; and constitutional reform. It is hoped that these recommendations will bridge the gap between customary law and western law as we endeavour to determine the future of the African marriage in a contemporary traditional context.

- Description: This study assessed the importance of overwash and breaching events on the ichthyofaunal community structure in the medium-sized temporarily open/closed Mpekweni Estuary located on the southeast coastline of southern Africa. The fish in the littoral zone of the estuary were sampled using a 5m seine net while the channel region was sampled using two nets, a smaller meshed 30m seine net to target the estuarine spawning species and the juvenile estuarine-dependant marine spawners, and a larger meshed 50m seine net to target the larger marine and freshwater spawning species. Intensive monthly sampling over two years provided data on selected physico-chemical and biological parameters. During the two year sampling period from November 2005 to October 2007 the estuary breached in late July 2006 and remained open till the sandbar re-formed across the mouth in late December 2006. Thus, sampling encompassed three open/closed phases 1) initial closed period, 2) open period and 3) re-closed period after the berm was re-formed. The open period was divided into two phases 1) the out-flow phase and 2) the tidal phase. A total of 36 fish species representing 19 families were sampled using the various seine nets employed during the investigation. In the littoral zone, the estuarine spawners (Estuarine Utilisation Category, [EUC] I), mainly the Gobiidae, Glossogobius callidus, dominated the samples numerically and by biomass. The smaller estuarine spawning species sampled in the channel were numerically dominated by Gilchristella aestuaria in conjunction with two other EUC I species, Atherina breviceps and G. callidus. The estuarine-dependant marine spawners (EUC II), however, dominated the ichthyofaunal biomass of the channel. The abundance and biomass of the larger species targeted were dominated by estuarine-dependant marine spawning species (EUC II), principally Rhabdosargus holubi. During the closed periods of the estuary, total fish abundance and biomass displayed weak seasonal patterns. The breaching event and subsequent open period was associated with a decrease in the total abundances of fish in the littoral zone and channel of the estuary, reflecting the out-flow of estuarine biomass-rich water into the marine environment. The breaching event coincided with a shift in the community composition of the ichthyofauna, reflecting the recruitment of marine spawning species into the estuary. Numerical analysis identified two distinct spatial fish communities within the estuary, a community associated with the mouth region and one comprising the rest of the estuary. The absence of any further spatial patterns in the ichthyofaunal community structure within the Mpekweni Estuary appear to be ascribed to the virtual absence of horizontal patterns in physico-chemical and biological parameters recorded in the system. Cohort analyses were employed to determine possible recruitment events for selected estuarine and marine spawning species. The estuarine spawning species displayed continuous recruitment patterns throughout the study, which appeared to be unaffected by the breaching event. Conversely, the larger marine spawning species displayed multiple cohorts, indicating non-continuous recruitment. Subsequent retrospective analysis of cohorts for the different species identified summer recruitment peaks that coincided with the breaching event and open period. Minor recruitment of marine spawning species also occurred during overwash events. The recruitment of ichthyofauna into the estuary was quantified during three distinct hydrological events: overwash, out-flow phase immediately after breaching and tidal phase during the period when the mouth was open. Estimates of fish recruitment were highest during the outflow phase immediately after the estuary breached and declined as the estuary became tidally inundated with marine water. Although not as high as the outflow and tidal phases, recruitment was evident during overwash events. Results of the current study highlight the importance of both breaching and overwashing events in structuring the ichthyofaunal community composition in a medium-sized southern African temporarily open/closed estuary. These results are broadly in agreement with similar studies conducted both locally and in other regions of the world.

During the two year sampling period from November 2005 to October 2007 the estuary breached in late July 2006 and remained open till the sandbar re-formed across the mouth in late December 2006. Thus, sampling encompassed three open/closed phases 1) initial closed period, 2) open period and 3) re-closed period after the berm was re-formed. The open period was divided into two phases 1) the out-flow phase and 2) the tidal phase. A total of 36 fish species representing 19 families were sampled using the various seine nets employed during the investigation. In the littoral zone, the estuarine spawners (Estuarine Utilisation Category, [EUC] I), mainly the Gobiidae, Glossogobius callidus, dominated the samples numerically and by biomass. The smaller estuarine spawning species sampled in the channel were numerically dominated by Gilchristella aestuaria in conjunction with two other EUC I species, Atherina breviceps and G. callidus. The estuarine-dependant marine spawners (EUC II), however, dominated the ichthyofaunal biomass of the channel. The abundance and biomass of the larger species targeted were dominated by estuarine-dependant marine spawning species (EUC II), principally Rhabdosargus holubi. During the closed periods of the estuary, total fish abundance and biomass displayed weak seasonal patterns. The breaching event and subsequent open period was associated with a decrease in the total abundances of fish in the littoral zone and channel of the estuary, reflecting the out-flow of estuarine biomass-rich water into the marine environment. The breaching event coincided with a shift in the community composition of the ichthyofauna, reflecting the recruitment of marine spawning species into the estuary. Numerical analysis identified two distinct spatial fish communities within the estuary, a community associated with the mouth region and one comprising the rest of the estuary. The absence of any further spatial patterns in the ichthyofaunal community structure within the Mpekweni Estuary appear to be ascribed to the virtual absence of horizontal patterns in physico-chemical and biological parameters recorded in the system. Cohort analyses were employed to determine possible recruitment events for selected estuarine and marine spawning species. The estuarine spawning species displayed continuous recruitment patterns throughout the study, which appeared to be unaffected by the breaching event. Conversely, the larger marine spawning species displayed multiple cohorts, indicating non-continuous recruitment. Subsequent retrospective analysis of cohorts for the different species identified summer recruitment peaks that coincided with the breaching event and open period. Minor recruitment of marine spawning species also occurred during overwash events. The recruitment of ichthyofauna into the estuary was quantified during three distinct hydrological events: overwash, out-flow phase immediately after breaching and tidal phase during the period when the mouth was open. Estimates of fish recruitment were highest during the outflow phase immediately after the estuary breached and declined as the estuary became tidally inundated with marine water. Although not as high as the outflow and tidal phases, recruitment was evident during overwash events. Results of the current study highlight the importance of both breaching and overwashing events in structuring the ichthyofaunal community composition in a medium-sized southern African temporarily open/closed estuary. These results are broadly in agreement with similar studies conducted both locally and in other regions of the world.

- Description: The demand for university education has increased at a higher rate than the resources available for universities to offer the required services. In Kenya, the demand for university education has continued to rise with university enrolment increasing tremendously over the last four decades. This growth calls for an investigation to find out the impact of this expansion on service delivery in universities. Kenya has thirty-nine fully-fledged universities that have been accredited by the Commission for University Education (as at 31st March 2013). Twelve others are operating with interim letters of authority (ILO). This development has created competition amongst universities and, as a result, necessitated the development of strategies to ensure survival in this changing environment. The review of existing literature on this subject has established that service delivery is a service differentiator and therefore could be utilised by universities to gain a competitive advantage and therefore enhance their overall performances. Based on this background, this study sought to establish the influence of service performance measurement on service delivery in relation to the expectations of university students in Kenya. Secondary sources were used to formulate a theoretical model of the influence of service performance measurement on service delivery that guided this study. The theoretical model indicates that non-academic aspects, academic aspects, reputation, programme issues and access factors may influence service delivery at the university. These five dimensions were used in the study as the independent variables of service delivery at the university. The outcomes of service delivery at the university were identified as student expectations, student satisfaction, student loyalty and student retention in the theoretical model; these were treated as dependent variables. Hypotheses were formulated that proposed relationships between the independent variables and service delivery. Hypotheses in respect of relationships between service delivery and the outcomes were also developed. A quantitative research approach was adopted to empirically evaluate the relationships between service delivery and the variables in this study. Data for the study was collected through the use of a structured self-administered questionnaire that was distributed to 720 university students in Kenya. Six hundred and thirty useful survey responses were received from fifteen universities. The data collected was subjected to factor analysis and multiple regression analysis to test the hypothesised relationships between the variables and service delivery. Descriptive statistics were also obtained from the raw data. The findings of this study indicate that non-academic aspects, academic aspects and access factors have positive and significant influence on service delivery in Kenyan universities. The quality and adequacy of academic, entertainment and sports facilities together with increased accessibility to services by students are important factors that influence service delivery at a university. The university students would like to be treated with respect and courtesy by academic and administrative staff during these service encounters. The empirical results of the study also reveal that student perceptions of service delivery impacts positively on student expectations, student loyalty and student retention related to convenience as well as student retention related to quality assurance.

- Description: This study examines the topic of the interaction of children’s rights, education rights and freedom of religion in South African schools from a legal perspective. It comprises of a discussion on the historical development of religion in South African schools; South Africa’s international obligations with regards to children’s rights, education rights and freedom of religion and the South African substantive law pertaining to children rights, education and freedom of religion as impacting on legal issues pertaining to religion in schools. The study utilises a desktop approach, which comprises of a wide range of legal and other literary sources, international instruments, statutes and case law on children’s rights, education rights and freedom of religion. Importantly, it highlights the integral connection between these aforementioned rights when dealing with issues pertaining to religion in schools. This thesis illustrates that much of the historical development of religion in schools took place without consideration of children’s rights, or more particularly, the best interests of the learners. Instead, (a particular brand of) religious beliefs were promoted in education above other religions and the well-being of school-children. Furthermore, despite the introduction of specific children’s rights into the Constitution, this thesis emphasises that the rights of children have still not been recognised sufficiently in education laws and policies. It is submitted that children’s rights have a paramount and practical role to play in matters pertaining to religion in South African schools. Consequently, it is recommended that children’s rights, more particularly the best interests of the child principle, should be expressly introduced into education legislation and policies. This will create legal obligations for school administrators and SGBs on the inclusion of children’s rights in religious exemption procedures. Furthermore, it is recommended that national guidelines on religious/cultural exemptions (which incorporate children’s rights) be developed which will set legal parameters for the handling of religious/cultural exemption procedures in schools. This thesis also argues against the interpretation that the right to establish private schools includes the right to require religious conformity from non-adherent learners by way of a complete waiver of their religious freedom. Despite the importance of respecting the right of religious communities to protect and preserve their faith in private schools, it is submitted that this right cannot be exercised without regard for the religious freedom, dignity and best interests of non-adherent children. As a result, it is submitted that the waiver of the freedom of religion of non-adherent children is not consistent with the values which South African society reveres and therefore cannot be enforced. This thesis suggests that there is a way for the rights of private schools and the rights of non-adherent children to co-exist in harmony through the application of the reasonable accommodation principle in private schools. Reasonable accommodation of different faiths teaches religious tolerance to leaners in private schools and ensures that they are prepared to grapple with the religious diversity that they will inevitably face outside of the school environment. It is submitted that the enforcement of reasonable accommodation in private schools is to the benefit of all learners in private schools and to South African society in general. Moreover, this study questions and analyses the state’s provision of compulsory religion education in public schools through the National Policy on Religion and Education. A theoretical distinction is made between religion education and religious instruction in the National Policy itself. Religious instruction refers to the teaching of specific religious beliefs. Religion education refers to the teaching about different religions and worldviews from an academic perspective. It is submitted that the National Policy is correct in removing religious instruction from public schools as this would not be in accordance with freedom of religion or equality rights of learners who are not of the majority faith. It is submitted further that, although the provision of compulsory religion education in public schools impacts upon the freedom of religion of learners and their parents, (if taught correctly) it is a reasonable and justifiable limitation on freedom of religion in that it pursues the legitimate state goal of nation-building through the teaching of religious tolerance and “celebrating diversity” in schools. In light of South Africa’s history of religious discrimination, it must be recognised that the current position (although not problem- free) is a significant step forward in the protection of minority religious rights in South African schools. Despite this, it is submitted that there are numerous problems with the implementation of the National Policy that impact upon the dignity, equality and other rights of the learners concerned. These problems cannot be ignored since they impact upon the daily lives of school children. However, many of these problems can be minimised through more effective teacher training in this subject area. Accordingly, this thesis recommends that the current position be maintained as an acceptable compromise between the two extremes of providing religious instruction in one faith and removing religion education from public schools altogether. However, it emphasises that the state has to make a concerted effort to improve teacher training in this subject area in order to ensure that the objectives of the National Policy are carried out as envisaged. Furthermore, this thesis finds that certain provisions of the National Policy contain not only educational goals, but spiritual goals. Also in some instances, it is difficult to determine whether the religion education curriculum borders on being religious or not. In accordance with freedom of religion, it is submitted that the line between religion education and religious instruction must be clearly drawn in law and in practice. Consequently, the state must reconsider the National Policy and the corresponding religion education curriculum to ensure that they are aligned with the objectives of nation-building in all respects, meaning that any provisions or learning outcomes which have purely spiritual goals- must be amended or removed.

- Description: This study investigates the interface between financial and marketing management in South African businesses by investigating the financial and marketing-management processes. This process orientation highlighted important interactions between the two functions. A critical analysis of secondary resources produced a clear theoretical foundation on which the development of the proposed interface framework was based. The critical literature analysis indicates four steps in the financial management process, namely, financial analysis, financial decision-making, financial planning and financial control (independent variables) and five steps in the marketing management process, namely, understanding the marketplace as well as customer needs and wants, designing a customer-driven marketing strategy, constructing an integrated marketing programme, building profitable relationships and capturing value from customers in the form of profits and customer equity. These steps were used to derive a proposed theoretical framework that shows how the steps in the financial-management process relate to those in the marketing-management process. The framework also indicates the perceptions of managers on the interface between the two functions. The perceptions on the interface include aspects such as the level of communication between the two departments, the understanding of each other‟s function and the flow of information between the two departments. From this framework, the six hypotheses were formulated to test the proposed relationships. The focus of the study is on the interface between financial management and marketing management; therefore, the population of this study comprised of financial and marketing managers in South Africa. The primary data relating to the interface between financial management and marketing management was acquired by means of an on-line web-based survey. Descriptive statistics was used to present, analyse and interpret the results of the data analysis. Various inferential statistical techniques (T-tests and chi-squared tests) were employed to determine whether respondents‟ perceptions of the items in the measuring instrument differed as result of whether they were employed in the finance or marketing sections of the business. Correlations (Pearson Product Moment correlations) were calculated for the purpose of investigating the relationships between the financial and marketing management variables used in this study. Factor analysis showed that financial management consisted of four factors that corresponded with the steps in the process, and marketing management produced five factors that related to the steps in the marketing management process. Lastly, statistical tests (MANOVA) were conducted to determine whether the perceptions of respondents, with regard to the financial and marketing management variables, were influenced by selected demographic variables. The results of the empirical study indicated positive relationships between all the variables in the framework. The marketing management factors, namely, mix and profit, reported the lowest correlations compared to the financial management factors. It was also found that financial and marketing managers had different perceptions of the steps in the financial-management process but that they did not have different views of the steps in the marketing-management process. Furthermore, financial and marketing managers had different opinions about the long-term perspective of the business as well as conflicting views with regard to the flow of information from finance to marketing. Financial managers were of the opinion that marketing managers did not understand financial methods and procedures and were unable to specify their requirements to finance. The proposed framework could be seen as the start of marketing theory development on finance interaction as it showed that interface relationships could be further explored.

- Description: Integrated Quality Management System (IQMS) consists of three policies, namely; the Developmental Appraisal System; Whole School Evaluation and Performance Management System, designed to foster a culture of continuous improvement in schools. However research has cast doubt on the integration of the three policies. It has been argued that the implementation of the three policies is fragmented, with diverse goals, multiple purposes, values that are at variance, and conflicting expectations, causing tension between personal needs and improvement needs. The aim of this study is to understand how IQMS practices and systems promote continuous improvement. This was a case study of four primary schools located in different contexts in East London District. In-depth interviews were conducted on a total of 12 participants across all the schools. There were three main findings. First, IQMS is understood and practised as an external intervention. It appears not to have been internalised as a quality management system. Second, the participants were ambivalent about the IQMS practices as enablers and as barriers of continuous improvement. A fair amount of educators did not view IQMS as daunting as some had portrayed it. Third, There were blurred lines between what participants recognised as systems and the actual practices in the implementation of the three IQMS policies . There was no evidence of systemic thinking on the part of practitioners. As far as the IQMS systems and practices are concerned, no direct mention of evaluation variables or paradigms can be found, making it somehow complex for educators to distinguish between identifiable systems and practices. Finally, the external and internal quality assurance practices seemed to have been subsumed under managerial imperatives of compliance and accountability. Educators revealed that they merely undertake the process as they are compelled to do so as an expectation or requirement by the Department of Education. Given the above findings it can be concluded that and if continuous improvement is to be achieved through the IQMS strategy, there is a need to re-invent it such that , embedded in its systems and structures is a culture of continuous improvement. The reconfiguration of IQMS should look for mechanisms for integrating the three policies. The study recommends, for practice there should be a balance between professional development of educators and managerial imperatives that demand compliance and accountability. Further study must be undertaken to unravel the three IQMS policies.

The redemptive life story of Glenda Watson-Kahlenberg: a psychobiography

- Description: This psychobiography is focused on the life of Glenda Watson-Kahlenberg, whose life history epitomises the redemptive theme of triumph over tragedy. A phenomenological approach to the study allowed the researcher to observe the participant‟s lived experience through the theoretical lens of Frankl‟s conceptualization of a meaningful and full existence. A holistic perspective of factors contributing to redemption was accommodated by the Biopsychosocial-spiritual Model. The aim of this longitudinal revelatory study was to illuminate the process of redemption in a life, which leads to restoration and wholeness. This study breaks with traditional psychobiography – in that a life in progress has been selected; and personality development is not the key focus. This psychobiographical undertaking was anchored in qualitative research in the form of a single case study. Four types of triangulation were utilized, namely: data, investigators, theory and methodological triangulation. In addition, Alexander‟s identifiers of saliency, Miles and Huberman‟s data-management guidelines, Schultz‟s prototypical scenes, and Guba‟s criteria for trustworthiness, guided the methodology to ensure reliable data extraction and interpretation. The present researcher was in search of a deeper understanding of the enabling factors facilitating a restorative process in a life that was challenged by setbacks. Given the increasing pressures facing individuals in this modern era, the redemptive theme holds particular relevance, and was graphically demonstrated in the life of the participant who experienced trauma, widowhood, divorce, single parenthood, and a spate of medical and psychological setbacks. The findings suggest that the mental health clinician‟s utilisation of Frankl‟s conceptualisation of meaning in the most challenging circumstances, proffers itself as an all-purpose life-tool which enables individuals to overcome their challenges. The study demonstrated that gaining meaning in life is inextricably tied to an implicit legacy-oriented worldview. Of significance, is the role of forgiveness which emerged as the central redemptive catalyst. In this study, the resolution of past hurts through forgiveness, and the search for meaning, merge, forming an arterial theme in the life story of the participant. The dual impact of these factors not only reversed contaminated life-scripts, it also birthed a new calling in life which set the participant on a generative life course. The findings related to a redemptive life not only confirms existing theory, but also adds perspectives not previously considered. In addition, the findings related to the role of forgiveness has positive implications for the individual‟s physical and psychological wellbeing. Greater intentionality on the part of therapists to thread forgiveness into their practice, remains invitational in the light of the eugraphic impact demonstrated in this study.

- Description: This psychobiography is focused on the life of Glenda Watson-Kahlenberg, whose life history epitomises the redemptive theme of triumph over tragedy. A phenomenological approach to the study allowed the researcher to observe the participant‟s lived experience through the theoretical lens of Frankl‟s conceptualization of a meaningful and full existence. A holistic perspective of factors contributing to redemption was accommodated by the Biopsychosocial-spiritual Model. The aim of this longitudinal revelatory study was to illuminate the process of redemption in a life, which leads to restoration and wholeness. This study breaks with traditional psychobiography – in that a life in progress has been selected; and personality development is not the key focus. This psychobiographical undertaking was anchored in qualitative research in the form of a single case study. Four types of triangulation were utilized, namely: data, investigators, theory and methodological triangulation. In addition, Alexander‟s identifiers of saliency, Miles and Huberman‟s data-management guidelines, Schultz‟s prototypical scenes, and Guba‟s criteria for trustworthiness, guided the methodology to ensure reliable data extraction and interpretation. The present researcher was in search of a deeper understanding of the enabling factors facilitating a restorative process in a life that was challenged by setbacks. Given the increasing pressures facing individuals in this modern era, the redemptive theme holds particular relevance, and was graphically demonstrated in the life of the participant who experienced trauma, widowhood, divorce, single parenthood, and a spate of medical and psychological setbacks. The findings suggest that the mental health clinician‟s utilisation of Frankl‟s conceptualisation of meaning in the most challenging circumstances, proffers itself as an all-purpose life-tool which enables individuals to overcome their challenges. The study demonstrated that gaining meaning in life is inextricably tied to an implicit legacy-oriented worldview. Of significance, is the role of forgiveness which emerged as the central redemptive catalyst. In this study, the resolution of past hurts through forgiveness, and the search for meaning, merge, forming an arterial theme in the life story of the participant.

- Description: The most recent surveys in South Africa estimate that invasions are still increasing, despite substantial clearing efforts. Riparian systems in South Africa are particularly vulnerable to invasion by woody IAPs. This thesis addresses the restoration of alien‐invaded riparian systems, by investigating the factors that facilitate or constrain spontaneous recovery and influence the trajectories of succession. These factors include invasion history and management history, especially the use of fire. A seedling emergence approach was used to test the presence of a viable pre‐fire seedbank, and the effect of fire on the seed bank. The efficacy of some active restoration interventions was also tested, with the aim to return invasion‐resistant, indigenous vegetation with a structure and function representative of uninvaded sites. The findings of this study indicated the presence of a viable and persistent riparian soil seed bank, even after 30 years of intermtittent invasion as well as two fire cycles under invasion. It shows that the management practice of fell‐and‐burn resulted in high soil temperatures, and that this reduced the indigenous soil seed bank density, especially in the upper soil layer. Clear germination sequences and patterns of emergence over time for different species were observed during this study, with many species exhibiting delayed emergence relative to the timing of the fire event. It is proposed that manipulation of the season of fire could be used to selectively optimise the order of arrival and therefore superior recruitment of some species over others in the Eastern Cape fynbos, and thus alter the trajectories of recovery of vegetation towards a more desired state. Active restoration in the form of indigenous seed and plant additions resulted in a significantly higher indigenous cover after seven months, compared to a control (passive restoration) or restoring with grass. Indigenous cover and composition was also strongly influenced by lateral zonation, and some key guilds and species were missing or present in much lower densities compared to reference sites. Grass restoration significantly suppressed the regeneration of A. longifolia, as well as the regeneration of indigenous species. Biotic resistance can thus be achieved through restoration, and it could be a powerful tool in the management of IAPs, although the deliberate introduction of grass after clearing in fynbos also reduces biodiversity and could have unforeseen consequences to riparian function.

- Description: This study set out to establish the role of conflict Management in Maintenance of Discipline in Kenya’s Public Secondary Schools. The study formulated 6 objectives as follows: examine the nature of Conflict experienced in Public Secondary Schools in Kenya; establish how teachers and students perceive conflict in secondary schools; determine how teachers and students experience conflict in Secondary Schools; investigate the effectiveness of conflict Management Programmes used in Secondary Schools; discover suitable conflict management programmes to address present and future conflict in secondary schools; generate findings based on a theoretical approach for understanding and managing conflict in secondary schools with particular reference to schools in Kenya. The research was conducted in the form of a descriptive survey design with a mixed methods approach which combined qualitative research design and quantitative research technique. A sample of 649 Students, 16 secondary school head teachers, and 16 secondary school guidance and counseling officers from 4 provinces in Kenya was used to obtain data for the study. Random and purposive sampling techniques were used. Data was collected using questionnaires and structured interviews. Descriptive statistics such as mean, percentages, standard deviation, and frequencies was used to discuss the research findings. The study also used inferential statistics, particularly chi-square to test the significant statistical differences on the nature of conflict in schools, how students and teachers experience and perceive conflict in different categories of schools. From the findings, students witness conflict in form of theft, 51.7%, bullying, 29 percent, rumours and fights. Results from males and females indicate that drugs are abused in secondary schools (males (26.8%) and females (13.6 percent). All the respondents revealed that students take drugs to please their peers, and to release stress, and for adventure. On the effectiveness of conflict management programmes, a majority of students accept punishment when they break the school rules (80.0%) as they feel that punishments improve their behaviour. Most of the teachers had not had proper training in conflict management and some of them do not understand the role of peer mediation as they lack such programmes in their schools. The study concluded that failure to train teachers in conflict management skills, and to involve students in decision making causes conflict in schools. The study recommended that life skills, and peace keeping lessons should be taught in schools. In addition, head teachers and teachers should go for a refresher course in conflict management. Also, the study recommends that a comparative study should be done in a wider scope in secondary schools that experience conflict and those that do not, so as to get an insight of the suitable strategies needed to manage conflict in schools.

- Description: In South Africa, the Labour Courts have experienced an important and continuing controversy regarding the permissible scope of judicial review of arbitration awards of the Commission for Conciliation Mediation and Arbitration (“CCMA”) in terms of section 145 of the Labour Relations Act 66 of 1995 (“LRA”). Section 145(1) of the LRA specifically provides that arbitration awards, generally considered final and binding, can be reviewed and set aside by the Labour Court on the basis of a defect as defined in section 145(2)(a) and (b). These defects are not prescribed in an open-ended manner but limited to decisions involving allegations of misconduct by the commissioner in relation to his or her duties, a gross irregularity in the conduct of the proceedings and/or allegations that the commissioner exceeded his or her powers or that the award was improperly obtained. Unreasonableness and/or irrationality are not included within the scope of a defect as per section 145(2)(a) and (b). Initially, Carephone (Pty) Ltd v Marcus NO & others 1998 11 BLLR 1093 (LAC) found that the interpretation of section 145 was influenced by rational justifiability in accordance with the right to just administrative action as provided for in section 33, read with item 23(2) of Schedule 6, of the Constitution of the Republic of South Africa, 1996 (‘the 1996 Constitution’). Today, leading precedent in the form of Sidumo & another v Rustenburg Platinum Mines Ltd & others 2007 12 BLLR 1097 (CC) dictates that section 145 of the LRA is suffused by reasonableness in accordance with the right to just administrative action as provided for in section 33 of the 1996 Constitution. The ultimate enquiry is whether the arbitration award is one that a reasonable decision-maker could reach as articulated in Bato Star Fishing (Pty) Ltd v Minister of Environmental Affairs and Tourism and others 2004 4 SA 490 (CC). However, the enquiry into the reasonableness of a decision is indistinct. As a result, the Labour Courts have struggled to apply the concept of reasonableness in a consistent manner. This thesis seeks to identify the proper role of reasonableness in the judicial review process, including identifying factors that would assist in recognising an unreasonable decision. Relevant principles of judicial review in South Africa in the general administrative law context are considered and distinguished from the process of appeal. An assessment of English case law and commentary in the field of both administrative and employment law is conducted. Finally an extensive examination of South African case law and commentary on the subject, both pre- and post Sidumo, is undertaken. The English law approach is found to provide greater clarity to the interpretation of reasonableness in South African labour law in several respects.

- Description: Breast cancer is a leading cause of cancer death in Africa. Hsp90 has been identified as a target for anti-cancer treatments as its inhibition results in the disruption and ubiquitin–proteasome degradation of activated oncoproteins. Currently, there are no US Food and Drug Administration approved Hsp90 inhibitor drugs and existing Hsp90 inhibitors such as geldanamycin and novobiocin are hepatotoxic and display a low affinity for Hsp90, respectively. Therefore, there is a need for the development of Hsp90 inhibitors with improved inhibitory properties. In this study twelve natural compounds bearing a quinone nucleus were screened and characterised for the modulation of Hsp90. The compounds analysed formed three series; the sargaquinoic acid (SQA), naphthoquinone, and pyrroloiminoquinone alkaloid series. Certain compounds exhibited half maximal inhibitory concentrations of between 3.32 μM and 12.4 μM, while others showed no antiproliferative activity at concentrations of up to 500 μM in the MDA-MB-231 breast adenocarcinoma cell line. Immunofluorescence and Western analyses indicated that the modulation of Hsp90 and partner proteins by SQA was more similar to that of novobiocin. Isothermal titration calorimetry analyses suggested that SQA interacted with Hsp90β with a low affinity, and saturation-transfer difference nuclear magnetic resonance confirmed that this interaction with Hsp90β occurred through the methyl moiety bound to 1, 4 benzoquinone of SQA. Pulldown assays indicated SQA disrupted the association between Hsp90 and Hop dose-dependently, more similarly to novobiocin. Immunofluorescence and Western analyses performed on naphthoquinone and pyrroloiminoquinone alkaloid compounds indicated modulation of Hsp90 and Hsp90 partner proteins by the compounds. Naphthoquinone compounds were prioritised for analysis for binding to Hsp90β over the pyrroloiminoquinone alkaloid compounds. Lapachol interacted with Hsp90β with a low affinity however; this interaction was thought to be too weak to disrupt the association of Hsp90 and Hop. The remaining naphthoquinone compounds showed no interaction with Hsp90β, thus allowing the determination of a preliminary structure-activity relationship for these compounds. To the best of our knowledge, this is the first study to describe a systematic subcellular analysis of the effects of geldanamycin and novobiocin in comparison to sargaquinoic acid and compounds of the naphthoquinone and pyrroloquinoline scaffold on Hsp90 and its partner proteins. , Microsoft� Word 2010 , Adobe Acrobat 9.54 Paper Capture Plug-in
