Anthropogenic disturbance from urbanization has introduced a range of contaminants into freshwater ecosystems. Wastewater Treatment Works (WWTW) in particular, deposit effluent with high metal concentrations directly into rivers. These pollutants may affect river biota directly or through modifications to habitat and prey. Therefore, the impact of metal pollution through a food chain should be evident in high trophic level predators such as Neoromicia nana. N. nana is a small, insect-eating bat that occurs in forest and riparian habitats in Africa. Most importantly, it is an urban exploiter, i.e. a species that takes advantage of anthropogenic food and habitat resources. I investigated the foraging behaviour and metal content of N. nana at wastewater-polluted sites (WWTW sludge tanks and sites downstream of wastewater discharge into the rivers) and unpolluted sites (sites upstream of wastewater discharge) at three urban rivers in Durban, South Africa, during winter and summer. To assess water quality, I determined cadmium, copper, chromium, iron, nickel, zinc and lead concentrations using Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES). To investigate the foraging behaviour of N. nana, I quantified relative N. nana abundance, and feeding activity from recorded echolocation calls. Using ICP-OES, I quantified metal concentrations in three tissues (liver, kidney and muscle). My results show that concentrations of most metals were generally lowest upstream, intermediate at downstream sites and highest at the tanks. The relative abundance and feeding activity of N. nana were significantly higher at wastewater-polluted sites than at upstream sites, despite there being significantly more insect orders upstream. However, pollution-tolerant Chironomidae (Diptera), were significantly more abundant at wastewater-polluted sites. Indeed, at wastewater-polluted sites, Diptera represented the highest percentage of insects in the diet of N. nana. Essential metals (copper, zinc and iron) were detected in all tissue samples of N. nana. In contrast, the toxic metals cadmium, chromium and nickel were present in tissue of bats only at wastewater-polluted sites (except one upstream occurrence of cadmium). This suggests that these metals may accumulate in tissue through the ingestion of pollutant-exposed prey. Thus, metal pollution from WWTWs affects not only water quality of rivers, but also the diversity of resident aquatic insects and ultimately the ecology of N. nana populations, which may pose serious long-term health risks for these top predators. / Thesis (M.Sc.)-University of KwaZulu-Natal, Westville, 2011.

The dissertation's point of departure and contention is that the Admiralty Reserve is one of the Coastal Resources facing degradation due to the fact that it is a common property owned by the State President on behalf of all citizens of South Africa. The environmental management function has become the unfunded mandate of local authorities therefore the administration, control and management of the Admiralty Reserve is the responsibility of local government in terms of various lease agreements. There are currently no specific tools available to local government to manage the Admiralty Reserve. The encroachment of the Admiralty Reserve has been and still is a problem for all coastal municipalities including Umdoni municipality. The rationale for the topic was to study the geography of the Admiralty Reserve, the causes of encroachments and the way in which the local authorities dealt (past and present) with the Admiralty Reserve encroachments; to assess the strategies employed by the municipalities in dealing with encroachments, and with the traditional and evolving functions of the Admiralty Reserve. This was done using standard research methods and techniques. The study is located in one of the small coastal municipalities of South Africa called Umdoni, in the Province of Kwazulu-Natal. The results of the study show that the past and present strategies of dealing with encroachments were adversarial in stance and not collaborative. The failure to administer and manage efficiently can be attributed to the following reasons: lack of capacity to deal with environmental matters and legislation, lack of political willpower, negligence on the part of both national and local government spheres, lack of stewardship, lack of proper education, training and knowledge of environmental issues and negative attitudes towards environmental matters. It was also revealed that generally people encroach into the Reserve because of greed and selfishness. One of the conclusions drawn from the findings was that the Admiralty Reserve has become a victim of fragmented control and management by various spheres of government. The Admiralty Reserve requires an integrated management approach that incorporates civic organizations, the relevant government departments, the local authority and the interested and affected individuals. Local authorities are not given proper tools to manage the Admiralty Reserve. There are many laws but none of them are relevant to the Admiralty Reserve. In the absence of usable legislative tools relevant to the Admiralty Reserve encroachments, it is highly recommended and imperative that coastal local authorities (particularly Umdoni Municipality) should formulate and strengthen their bylaws. / Thesis (M.Soc.Sc)-University of KwaZulu-Natal, Durban, 2005.

Tourism development in remote areas of South Africa is often being proposed as the solution to poor rural communities' development needs. However, experience indicates that tourism development can result in a negative impact on a community's culture and way of life. The issue of sustainable development and what it means sets a base in which the research looked at tourism in rural areas. The case study on the impact ofthe redevelopment ofLilani Hot Springs as a tourist resort focusses on both the people and environment. The historical context ofthe hot springs, their discovery, development and the demise ofthe old resort is investigated. This was undertaken so that lessons learnt from the past can be taken into consideration with the future development of the resort. This study has included investigating the viability and sustainability of such a tourist resort in the Umvoti Magisterial District and in a rural environment. By focussing on the Lilani community, this research project explores the key factors which have been identified as essential if long-term sustainable tourism is to be achieved in remote rural communities. An appropriate planning approach which stresses local participation and decision-making within the context of a holistic strategy for community development is subsequently proposed. Tourism has the potential ofprotecting the environment while providing social and economic benefits to the local communities. Clearly ifthe socio-economic needs ofthe local community in which a tourism development is set are not addressed, it will not succeed but ifthe natural environment, which is the very asset on which the tourism development is dependent upon, is not protected the resource which is the source of attracting tourists will be destroyed. / Thesis (M.Sc.) - University of Natal, Pietermaritzburg, 2000.

The Ngoye Granite Gneiss Formation is located in the Natal sector of the Proterozoic Namaqua-Natal Mobile Belt, about 10 km southwest of Empangeni. It forms a prominent east-west trending elongate whalebacked massif some 30 km in length, within amphibolitic gneisses and schists of the Tugela Group. A suite of twelve different, gneissic granitoids has been-recognised within the Ngoye Formation on the basis of field relationships, mineralogy and supportive geochemistry. They range in composition from peraluminous syenite to peralkaline granite. Peraluminous varieties are typically muscovite and garnet-bearing whereas metaluminous granites in the formation contain olivegreen biotite and/or hornblende and sphene. Riebeckite, aegerine and yellow-brown biotite, with accessory fluorite and zircon are characteristic of the peralkaline granites. Geochemically, the samples analysed display a range in SiO₂ from 63,79 - 78,47∞, are extremely depleted in CaO and MgO, while being enriched in Na₂O and K₂O. Depletion of CaO relative to alkalis is shown by an alkali-lime index of only 36, suggestive of an alkalic character. The agpaitic index (A. I. = mole Na₂O + K₂O/AL₂O₃) of the peralkaline samples ranges between 1,02 and 1,16; which classifies them as granites of comenditic affinity. Various chemical classification schemes have been tested and evaluated, of which the RI - R2 multicationic diagram provides results most similar to modally-derived terminology. Accordingly, the Ngoye granitoids are shown to range from minor syenites and alkali granites to predominant monzo - and syeno-granites. Trace element data indicate that the peralkaline granites are enriched in Nb, Zr and Zn relative to the other, non-peralkaline, granites in the formation. In addition, radioactive, magnetite-bearing quartz-rich rocks associated with the peralkaline granites, have extremely enhanced contents of Nb, Zr, Y, Zn, U, Th and to a lesser extent Sn and W. Peraluminous and near-peraluminous granites have the highst Rb/Sr and Rb/Ba ratios of all samples analysed, as well as enhanced Sn, U and Th contents while Zr is notably depleted. Small, muscovite-rich pods associated with muscovite-bearing granites are highly enriched in Sn. The application of certain discriminants based on modal and geochemical parameters has shown the Ngoye Formation to comprise typical "A" - type granites. "A" - type granites are characteristically intruded as ring complexes into anorogenic or post-orogenic tectonic settings in attenuated or epiorogenically-domed continental crust. Comparison of the Ngoye Formation wi th the well-known "younger granite" complexes of Nigeria and Saudi Arabia reveals marked similarities. The inference is therefore that the Ngoye Formation represents a metamorphosed "postorogenic" granite complex with most of the hallmarks of "A" type or "within-plate" magmatism. Four phases of deformation (D₁ to D₄) are recognised within the area mapped. Evidence of D₁ deformation is rare, but rootless folds within the transposed layering in the amphibolitic country rocks reflect the intensity of this prograde metamorphic event, M₁, during which upper amphibolite grades were achieved. Field evidence shows that the Ngoye granites were intruded after the D₁ event and prior to D₂. This latter event caused widespread folding about east-west F₂ axes, with the development of a pervasive S₂ planar fabric within the antiformally folded Ngoye Formation. S₂ is locally developed in the amphibolitic country rocks. The D₂ event culminated in the development of northward-directed overthrusting and retrogressive ,M₂, metamorphism of mylonitic thrust planes. Lateral shearing characterizes D₃, with development of macroscopic mylonites and mesoscopic conjugate shear zones. This was in response to a sinistral sense of movement, as indicated by prominent sub-horizontal extension lineations (L₃) and microscopic asymmetric augen structures. D₄ is deduced from stereograms and is indicated as cross-folding of F₃ fold axes. / Thesis (M.Sc.)-University of Durban-Westville, 1985.

This research focuses on KwaZulu-Natal case studies of land reform projects that serve as contributors to local economic development (LED). Key stakeholders and role players on LED matters within the KwaZulu-Natal province serve as respondents. The study seeks to answer critical questions regarding the success and viability of land reform projects. “Rural development is one of the the signature projects that swept the African National Congress (ANC) to power. It is supposed to distinguish the new administration from all that has gone before by having a dedicated ministry specifically to look after the forgotten countryside”, (Mabanga 2010, p. 36). For communities operating registered companies, some of the major challenges, amongst others, include a lack of farm management skills, business skills, financial skills and governance skills (including corporate governance). Leadership challenges are experienced between community members that ultimately may lead to the collapse of projects. There are also concerns regarding state support for post settlement. This affects the operation and capitalization of the projects and is required to kick-start projects after land transfers. Other challenges include skills shortage amongst managers and post settlement support for specific industries to ease transfer of skills to beneficiaries. The majority of the post-settlement support from the National Department of Rural Development and Land Reform has no, or limited, skills in specific industries like forestry, sugarcane, crop farming and animal farming. Consequently there is a shortage of proper advice to the community managers from inception and the incumbent official then still has to learn the industry operating systems. Ultimately all the parties rely heavily on consultants to provide assistance to newly emerging farmers or business entrepreneurs within the communities. The transfer of developmental grants is a major headache currently facing the majority of land beneficiaries. The department of rural development still owes communities post-settlement grants or development grants back-dated to the 2008/09 financial period. The objective of this study was to arrive at some guidelines and recommendations that will contribute to the success of land reform projects and thereby contribute to LED within KwaZulu-Natal province. / Thesis (M.Com)-University of KwaZulu-Natal, Westville, 2011.

This study looks at the effectiveness of transformation policies in addressing racial inclusiveness and equity issues in the workplace as well as the impact that stereotypes have on performance. Hence it is the purpose of this study to determine whether there is a mystery around black managers’ performance in comparison with their white counterparts, that is, performance of black managers tends to be seen as inferior and sub standard to that of whites. The primary problem of this study is to determine whether changing attitudes in the workplace can stimulate the environment for successful managers. There are a number of perceptions that whites have of black managers mainly around their performance and their ability to deliver on the job, hence the study looks at how attitudes (either positive or negative) impact on the black managers’ performance as well as how cultural influences shape a manager’s behaviour in the workplace. This study was exploratory in nature, which is a form of qualitative research. Qualitative research was deemed appropriate as the research looked at human experiences and perceptions i.e. managers’ experiences interacting with other racial groups namely black and white. This study was conducted through primary data collection where the data was collected through face-to-face interviews with the use of carefully drafted questionnaires. Based on findings of this study it is apparent that transformation policies such as Affirmative Action and Black Economic Empowerment are ineffective at achieving transformation within organisations, as they are not correctly implemented and therefore prone to abuse (lead to window dressing practices) and due to the fact that there is a great deal of negativity associated with these policies. The results also suggested that both black and white managers still had negative perceptions of each other. To some extent the negative perceptions demonstrated by white senior managers were one of the contributing factors to black managers’ poor performance although it is difficult to prove that the negative attitudes were the sole reason for black managers’ poor performance. / Thesis (MBA)-University of KwaZulu-Natal, Westville, 2011.

This research focuses on policy networks as a framework to analyse the implementation of the South African Land Reform (Labour Tenant) Act 3 of 1996 (LTA) and the Extension of Security of Tenure Act 62 of 1997 (ESTA) more generally. In particular, this research looks at the Association for Rural Advancement’s (AFRA) implementation of the farm dwellers project, specifically, how this organisation has been using the policy networks approach to implement its farm dwellers project. The LTA and the ESTA guide the South African post-apartheid land reform programme. This programme responds to the racially-based system of land access created by colonialism and apartheid. It is against this system of land access that the post-apartheid, democratic government undertook a vast land reform programme, intended to redress the injustices of the past (Drimie 2003:39). The LTA and ESTA are situated within this perspective and their objectives were derived from an understanding that land reform has the potential to make a direct impact on poverty through targeted resource transfers and by addressing the economic and social injustices caused by colonial and apartheid dispossession. However, after sixteen years of democracy and policy implementation of the land reform programme, little progress has been made. This includes an undertaking in the Reconstruction and Development Programme (RDP) of 1994, which provided a set of guidelines and principles for the evolving land policy, to redistribute, by 2014 (extended from 1999), 30% of the 80% of commercial farmland (mostly white owned) to black South Africans and to make land reform the driving force of rural development (Drimie 2003:39). By March 2009, a total of 5.2% of the targeted 30% of commercial farmland has been transferred through the various land reform programmes (Kleinbooi 2009:1). Concerns have been raised that attribute this seeming failure of the land reform programme to the government’s market approach (Mkhize 2004). This has been sustained by the government’s shift from the RDP to Growth, Employment and Redistribution (GEAR). AFRA, in its funding proposal of 1998-2000, has identified this shift as “disturbing because it implies that government’s economic and political direction is likely to result in reduced resources for rural and agricultural development, a shift which will impact hard on the already tough conditions of poverty that people live in.” From this understanding, this research hopes to establish that the seeming failure of the implementation of the South African land reform can be improved through a more effective utilisation of policy networks. More particularly, this research hopes to establish how AFRA has been using policy networks to implement its Farm Dwellers project from 1994 until today. / Thesis (M.Soc.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2010.

Skills shortages in South Africa occur when demand for certain skills exceeds supply, South Africa has a high demand for mathematical, sciences and information technology (IT) related skills (Daniels, 2007:1). Factors such as HIV/AIDS, legislation (for example affirmative action), and rapid growth of the IT sector and the education system are contributing to the continuous increase in the skills shortages rate in South Africa (Daniels, 2007:1). As a result of the skills shortages, South African organisations find themselves competing with international organisations for managerial-level employees, resulting in a ‘war for talent’. This study specifically focussed on the incidence and reasons associated with managerial-level employees’ intentions to leave their KwaZulu-Natal (KZN)-based organisations. In particular, the perceptions of MBA students studying at UKZN formed the focus of this study. The study, both primary and secondary data were collected and analysed. In the study the targeted population were managerial-level employees who were currently working in KwaZulu-Natal-based organisations and who had met the entry requirements of UKZN’s Graduate School of Business (GSB). The purposive sampling technique was used and all the registered MBA students at the GSB of UKZN formed the target population that is, the target population comprised of all 1st year, 2nd year and 3rd year MBA students and there were approached following that same order. In the study it was found that the three CFST sub-components that had the most influence on the managerial-level employees’ decision to leave were aspects of the CFST related to careerpath strategies, management/leadership style and rewards. These results were more clearly supported and given stronger evidence by the rankings of the high scoring samples of the intention to leave (ITL) scale and propensity to leave (PTL) scale which depicted the same three CFST sub-components. Recommendations were made based on the findings of the study that South African organisations have a strong influence on the respondent’s decisions to leave their organisations. It was also recommended that South African organisations should implement effective leadership/management style and should also offer their managerial-level employees competitive remuneration packages. / Thesis (M.Comm.) - University of KwaZulu-Natal, Pietermaritzburg, 2009.
