- Description: Countries should encourage their workforce to foster human development as it contributes to the economic development through having a well-trained and skilled workforce. The countries that are economically developed have stood out because of human capabilities that have triggered economic development. With innovation being one of the major advantages of human capital, new ideas lead to the creation of vast employment opportunities especially for those that have studied critical skill subjects. The economic status of Zimbabwe shows that there is human capital development happening in the country, but there is a serious shortage of skills in sciences, technology, engineering and mathematics that are necessary for the industrialisation of the country. The government believes that Zimbabwe can industrialise if STEM education is integrated in the country’s educational system to make human capital development wholistic. The study aims to understand the concept of human capital development and how it can be developed at a balance. A discussion on the primary role of universities and higher learning institutions on developing human capital will be done. Universities educate and equip students with knowledge and skills, hence both STEM and non-STEM curricula is needed to develop human capital that is balanced. This is because STEM graduates that are innovative can create jobs for non-STEM graduates and help a country to industrialise and develop its economy. Universities are recommended to increase public awareness of STEM, train teachers specifically for STEM, invest in research and development and develop STEM-related policies and systems to develop more STEM graduates to strike a balance with non-STEM graduates and enhance industrialisation in Zimbabwe. Interviews were conducted and analysed and some of the recommendations made were to encourage the government to deregulate to attract investment, to increase the public’s awareness of STEM and to train STEM teachers accordingly.

- Description: With the continued miniaturization of technology and the incorporation of Moore’s law, smartphones are more powerful. These mobile devices contain technologies that add other functionalities to them. Technologies such as sensors constantly provide information to the device. The constant stream of information from these sensors often leads to information overload of relevant and irrelevant information. To work towards solving this problem context-aware computing was introduced. Our major concern is that context information in context aware computing is not completely being utilized. The aggregation of context information could unlock more possibilities. This research seeks to aggregate the context of multiple devices such that, through analysis, some emergent behaviour can be observed. In this research context information from the sensors of devices is collected using an Android application and a central Server. The context information is used for pattern analysis. A pattern analysis algorithm is designed and used to observe patterns throughout the data set. It shows patterns that are similar within the dataset. In the case that the pattern observed has no similar pattern or few similar patterns this behaviour can be stated as emergent in the dataset. Further study of this emergent behaviour can be performed were a classifier can be used to give the exact activities that were being performed at that time. The research found this was possible and has many uses. One of these is in disaster prevention were the behaviour of a group of individuals may be monitored to observe any random changes such as masses running at the same time. This could be used as a first warning to natural disasters.

- Description: Education is a critical phenomenon which cannot be ignored as its effects cut across all spheres of life, especially the social and economic aspects. In the particular case of South Africa, education has been a serious issue of concern for a very long time and after the transition process took place in 1994 it became a priority on all agendas of governance. Expanding on the already existing debate about education in South Africa, this thesis specifically explores attitudes and perceptions about the knowledge acquisition process and experiences of Ngangelizwe youth graduates to understand the significance of education in their lives. As Freire wrote about the phenomenon of education from the point of view of the oppressed and marginalized in society, his theory explains and aids as a tool for careful analysis in this case. Moreover, considering that at the centre of Freire’s world view was the belief that humans have an ontological vocation to become more fully human, the youth graduates of Ngangelizwe became a good case as they live under conditions that one would regard as dehumanizing and oppressive. The youth graduates’ actions and attitudes would therefore guide and provide indication as to whether their education, both from academic spaces and the community, has empowered them to challenge the dehumanizing and oppressive nature of the dominant culture as a means to becoming fully human in their life and time, particularly in their community of Ngangelizwe. While the general finding has been that the participants’ education portrays both elements of banking and problem-posing education, it was also discovered that it all depends on the level and forces of education that the participants receive their inspiration from. This is due to the fact that education is not one dimensional, it begins from the moment one is born up until he or she no longer exists on earth. Therefore, education does not belong to one group of people; everyone has the ability to educate in as much as he or she has the ability to be educated.

- Description: We report on the conjugation of azide-derivatized gold nanoparticles (AuNPs) to alkyne moieties of ZnPc and InPc via azide-alkyne Huisgen cycloaddition reaction to form phthalocyanines-AuNPs (MPc-AuNPs) conjugates. The detailed structural characterizations of the composites were in good agreement with the expected results. The nonlinear absorption coefficients and other nonlinear optical limiting parameters were almost two times larger for the conjugates compared to free phthalocyanines. We established direct relationship between improved photophysical characterizations and enhanced nonlinear effects of reverse saturable absorption mechanisms favoured by excited triplet absorption of the phthalocyanines in the presence of AuNPs. The combination of InPc with AuNPs resulted in the lowest limiting intensity value of 0.06 J/cm2, hence the best performance in terms of optical limiting.

- Description: This study reports the development of functional optical limiting materials composed of pristine graphene (GQDs), nitrogen-doped (NGQDs) and sulfur-nitrogen co-doped (SNGQDs) graphene quantum dots covalently linked to mono-amino substituted zinc phthalocyanine (Pc). Open aperture Z-scan technique was employed to monitor the behaviour of the conjugates under tightly focussed Gaussian laser beam using a mode-locked Nd:YAG laser delivering 10 nanosecond (FWHM) pulses at 532 nm wavelength. Nonlinear effect due to reverse saturable absorption was the predominant mechanism; and was attributed to the moderately enhanced triplet population. The major factor(s) responsible for the enhanced nonlinearities in the Pc-NGQDs and Pc-SNGQDs was fully described and attributed to the surface defects caused by the presence of heteroatoms of N and S.

- Description: This work describes the synthesis, photophysical and nonlinear optical characterizations of alkynyl Pcs (1, 2, 3, 8 and 9), 1,2,3-triazole ZnPc (4), mercaptopyridine Pcs (5, 6 and 7) and amino Pcs (10 and 11). Complexes 1, 2, 4, 7, 8, 9 and 11 were newly synthesized and characterized using techniques including 1H-NMR, MALDI-TOF, UV-visible spectrophotometry, FTIR and elemental analysis. The results of the characterizations were in good agreement with their molecular structures, and confirmed the purity of the new molecules. Complex 10 was covalently linked to pristine graphene (GQDs), nitrogen- doped (NGQDs), and sulfur-nitrogen co-doped (SNGQDs) graphene quantum dots; gold nanoparticles (AuNPs); poly(acrylic acid) (PAA); Fe3O4@Ag core-shell and Fe3O4- Ag hybrid nanoparticles via covalent bonding. Complex 11 was linked to Agx Auy alloy nanoparticles via NH2-Au and/or Au-S bonding, 2 and 3 were linked to gold nanoparticles (AuNPs) via clicked reactions. Evidence of successful conjugation of 2, 3, 10 and 11 to nanomaterials was revealed within the UV-vis, EDS, TEM, XRD and XPS spectra. Optical limiting (OL) responses of the samples were evaluated using open aperture Z-scan technique at 532 nm and 10 ns radiation in solution or when embedded in polymer mixtures. The analyses of the Z-scan data for the studied samples did fit to a two-photon absorption mechanism (2PA), but the Pcs and Pc-nanomaterial or polymer composites also possess the multi-photon absorption mechanisms aided by the triplet-triplet population to have reverse saturable absorption (RSA) occur. Phthalocyanines doped in polymer matrices showed larger nonlinear absorption coefficients (ßeff), third-order susceptibility (Im [x(3)]) and second-order hyperpolarizability (y), with an accompanying low intensity threshold (Ium) than in solution. Aggregation in DMSO negatively affected NLO behaviour of Pcs (8 as a case study) at low laser power, and improved at relatively higher laser power. Heavy atom-substituted Pcs (6) enhanced NLO and OL properties than lighter atoms such as 5 and 7. Direct relationship between enhanced photophysical properties and nonlinear effects favoured by excited triplet absorption of the 2, 3, 10 and 11 in presence of nanomaterials was established. Major factor responsible for the enhanced nonlinearities of 10 in the presence of NGQDs and SNGQDs were fully described and attributed to the surface defects caused by the presence of heteroatoms such as nitrogen and sulfur. The studies showed that phthalocyanines-nanomaterial composites were useful in applications such as optical switching, pulse compressor and laser pulse narrowing.

- Description: The fairy tale genre has an extremely complex, yet interesting history and development. Originally created and used for the entertainment of adults, these tales traditionally included a wide range of themes, characters and gender dynamics than more recent, modern tales. This is because the original tales spoke to and included themes, characters and gender roles evident in the societal structure and time period in which each was written. Thus, traditionally patriarchal, gender-unequal societies generated tales which embodied this patriarchy and inequality. As society developed and gender relationship dynamics changed, writers of fairy tales began to alter the traditional tales, as they no longer suited the society’s outlook on life and gender. In addition to this, as the original tales were remade, the dynamic views of the society in which each was recreated, was then reflected. Therefore, this study’s primary focus is to investigate the development of the fairy tale genre, specifically the Sleeping Beauty tale, over the years and analyse the changes of the tale, with regards to patriarchal traditions, character traits and gender relationships. Within this work, the original tales of Charles Perrault and the Grimm Brothers, as well as the Sleeping Beauty remakes of Anne Thackeray Ritchie, Angela Carter, Robert Coover and Neil Gaiman will be analysed through the lens of feminism. Thus, each tale will be examined for their characters’ traits and gender relationships, and how these traits and relationships support and continue patriarchy and gender inequality, or question, challenge and provide alternatives for this patriarchy and inequality. In addition, the historical context of each author will be investigated in order to determine how each tale fits into the social context in which it was written and published. To conclude, through studying each Sleeping Beauty remake, this study has highlighted an interesting movement in fairy tale literature. As tales are published in more recent times, so their characters become altered from the typical and patriarchally expected gender roles and character traits. More and more, writers are creating characters that challenge the ‘norm’ of patriarchy. Therefore, this shows that in more modern times, societies’ structures are becoming more diverse and accepting of alternatives to traditional gender roles. Importantly, there is a wide sector of fairy tale literature which has not yet been examined in this way. The traditional fairy tales and their remakes include a number of interesting points that, as this study has proved in its analysis of Sleeping Beauty, can have a major impact on the study of the fairy tale genre as well as highlight developments in social structure and feminist thought.

Thermodynamic and electrical performance monitoring of a domestic split-type air conditioner and development of a simulation based R22 permanent replacement

- Description: The difficulty that exists in accurately monitoring the performance of air conditioners has made performance prediction an arduous task. Nevertheless, the performance still needs to be monitored and predicted as it helps solve a lot of problems resulting from this technology like effect of the technology on the grid, energy consumption, water utilisation and GHGs emission. With the introduction of regression modelling as a means of system monitoring and prediction some years ago, the accuracy was still a call for concern. It is worth realising that increasing the number of predictors will enhance this method’s accuracy. As such, this document intends to increase the accuracy of this method’s monitoring and predicting ability by increasing the number of predictors to cut across system thermal, environmental and human behavioural variation. These predictors experimentally gotten are used to build an environ-behavioural model that monitors the coefficient of performance and energy consumption of a domestic split-type air conditioner with higher accuracy. Refrigerants have undergone evolution in the past decades in a bid to come up with a refrigerant that has zero ODP, lower – than – R22 GWP and much better than R22 thermodynamic performance. No pure refrigerant has been found to possess these qualities as such mixtures or blends are the best shot at the moment. R410A could stand the test of time to be the long term R22 replacement but for the fact that besides R410A’s higher GWP than that of R22, the former’s system performance is lower than that of the latter’s due to the lower thermodynamic performance of the former. This means the search continues. In this document, a combination of carefully chosen refrigerant components are carefully blended to come up with a simulation based R22 long term replacement, which will be referred to in this document as BTEP.

In this document, a combination of carefully chosen refrigerant components are carefully blended to come up with a simulation based R22 long term replacement, which will be referred to in this document as BTEP.

- Description: This study was prompted by the prevailing imbalance in financial development across SADC countries, which is not consistent with the linkages and interconnectedness of financial systems of these economies. South Africa is the most financially developed country in Africa, yet it is surrounded by economies with relatively small and underdeveloped financial systems, contrary to the spatial proximity theory in finance. The study performed a number of empirical estimations in respect of the spatiality of financial development, motivated by the intention to assess the growth and spatial spill-over effects of financial development in SADC. The study provides new information in spatial spill-over dynamics of financial development, which could inform policy development particularly in view of the on-going financial integration in the SADC region. The study also contributes to regional economic development in SADC from a finance perspective. The analysis was performed using annual data for all the 15 SADC countries, spanning for the period 1985 to 2014. Using the Generalised Method of Moments approach, the study finds that financial development does not support economic growth in SADC. Financial reforms were found to be insufficient to drive growth. A bi-directional causality between financial development and economic growth was established with causality being strong when flowing from economic growth to financial development. The extended Aghion, Howitt and Mayer-Foulkes Model, estimated by an Autoregressive Distributive Lag approach, established that financial innovation has a positive relation to economic growth in SADC, particularly in the long-run. There is no causality, in either direction, between financial innovation and economic growth in both the short and long-run. The Spatial Durbin Model reveals a presence of positive spatial effects on financial development in the region and that proximity to South Africa yields consistent effects of spatial externality in money markets and inconsistent spatial externality in credit markets. The monetary union has no influence on spatial dynamics of financial development in SADC. The generalised impulse response analysis of a Bayesian VAR model indicate that shocks in South Africa’s financial sector has positive, but constrained and in some cases weak, financial spill-over effects on both economic growth and financial development of other SADC countries. The study established, using the Herfindahl-Hirschman Index, a high level of financial market concentration for SADC, cantered in South Africa, and a fair distribution when South Africa is excluded. Dynamic panel models established that financial market concentration reduces financial development in SADC. South Africa’s financial development has mixed and opposing effects on financial market concentration in SADC. The findings also show that international finance has a positive, but currently weak, effect on financial development in SADC and countries with international financial centres contribute more to financial development than countries without. Proximity to South Africa creates huge potential for increasing financial development in SADC through spill-overs and more benefits of spatial proximity are realised in the long-run. Given the strong spatial effects in money markets and significant positive spill-overs in credit markets in the region, countries closer to South Africa need to link their money and credit markets to the South African markets and possibly benchmark to the Rand so as to benefit from proximity and spill-overs from South Africa. The results also suggest that SADC countries need to capitalise on their proximity to South Africa to enhance financial development by promoting economic growth, financial innovation, opening and diversification of financial sectors and linkages to global financial markets. Financial innovation supports financial inclusion, cross-border flows of funds, remittances and trade in SADC and has effects of enabling integration with developed markets and facilitating economic activity. Opening financial sectors enhances diversification of financial systems, increases competition and efficiency. To enhance access to international finance, the study suggests the creation of information centres in South Africa with SADC countries as economic hinterlands, commercialisation of solutions to SADC countries financial challenges, financial integration and support for deepening of financial systems in these countries. Strengthening economic growth could also increase financial development given a strong demand-following causality. The major challenge, however, is that some of the SADC countries have underdeveloped and highly concentrated financial systems characterised by high financial intermediation inefficiencies, high financial exclusion, weak financial infrastructure and regulations. Consequently, countries suffer financial leakages, are not receptive to spatial externalities and financial spill-overs from South Africa and often generate financial spillbacks to South Africa. SADC countries should, however, first address the issue of financial exclusion, financial infrastructure and regulation as well as efficiency in the financial markets. The SADC countries need mechanisms to attract financial development from South Africa to benefit from positive spill-overs and instruments to deal with negative externalities of financial shocks in South Africa. Overall, there is potential for increased financial development in SADC by consolidating absorption of positive financial spill-overs and externalities of proximity to South Africa -particularly in the medium to long term. Heterogeneity among SADC countries and the varying levels of financial development, however, dictates that the region should promote financial integration in order to enhance development of underdeveloped financial systems through spatial spill-over gains.

Ecosystem engineering by the wetland plant palmiet: does it control fluvial form and promote diffuse flow in steep-sided valleys of the Cape Fold Mountains
- Authors: Barclay, Amy

- Description: Ecosystem engineering refers to the way that organisms control the structure and function of ecosystems. It has been suggested that palmiet (Prionium serratum, Thurniaceae) works as an ecosystem engineer, shaping peat wetlands in South Africa. However, there is currently a paucity of evidence supporting this claim. Palmiet has a dense root, rhizome and stem system that forms dense stands, growing from channel banks into fast flowing river channels. This slows river flows, traps sediment, which builds up riverbeds and ultimately blocks river channels, turning the river into a wetland. The aim of this study was to determine if palmiet is an ecosystem engineer and to document its pattern of colonisation and the nature of its control of a fluvial system. This was achieved by undertaking vegetation surveys in the Kromrivier Wetland in the Eastern Cape. The data was analyzed using vegetation classification and ordination, where vegetation communities were linked to environmental factors. It was found that palmiet occupied three distinctive habitats; 1) on near-horizontal valley- bottom habitats filled with sediments that are a mixture of autochthonous organic sediment and allochthonous clastic fines, 2) the bed of gullies that have recently filled with coarse grained clastic sediment, and 3) open water bodies. Three conceptual models were developed, one that accounts for the process of gully bed colonisation, sediment trapping and gully filling, another involving rapid colonisation of sedimentary fill from tributary sediment sources that block a gully, and the third involving colonisation of open-water areas that form in former gullies upstream of the blockage. The study suggests that the wetland has been characterised by repeated cutting and filling cycles, despite which, palmiet has repeatedly reinstated diffuse flow conditions across the valley floor. Palmiet was indicated to exert a key control on fluvial form and dynamics of the wetlands in the Kromrivier valley.

- Description: The term automotive industry is an umbrella term for concerns and undertakings contributing to the manufacturing of motor vehicles. This includes components such as engines, electronics, harnesses, interiors and shells, but excludes consumables such as tires, batteries and fuel. The local automotive industry is one of South Africa’s most profitable industries, funding more than 7% of the country’s GDP and contributing towards almost 12% of South Africa's manufacturing exports. Many multinational automotive manufacturers have invested in South Africa. This has allowed them to be strategically placed with the intention to source components, assemble and produce vehicles locally for the South African and other world markets. Due to the current contributions and its potential to grow the South African economy, the South African administration has recognised the automotive industry as an important sector. The South African government introduced the Motor Industry Development Programme during 1994 and the Automotive Production and Development Programme since 2013 to further stimulate the market and investment and further aims to increase the local production of vehicles to 1.2 million units per year as part of its 2020 vision. When considering the global competition, from China and Eastern Europe, it is imperative for the South African manufacturers to pursue and implement innovative practices to ensure that they can be competitive in the global arena, to retain and attract more multinational manufacturers to invest in the country and to ensure the future of existing multinational manufacturing facilities. Many scholars agree that intrapreneurship, also known as corporate entrepreneurship, is an approach which has the ability to help organisations to be more innovative and can guarantee competitiveness. Intrapreneurship is a valid and important aspect of entrepreneurial research. The subject of intrapreneurship can be divided into several key areas: 1. The individual operating as an intrapreneur within an organisation, focusing on his or her traits and the acknowledgement and support received within the organisation; 2. The conceptualisation and implementation of innovative projects from inside the organisation, focusing on the different departments and business units within the organisation’s corporate structure; 3. The entrepreneurial organisation, focusing on the core characteristics of the organisation. This study explores the concept of intrapreneurship, by consulting existing literature and then measuring the levels of intrapreneurship at a German automotive manufacturing plant in the Eastern Cape. To ensure anonymity of the organisation in which the study is conducted, it will be referred to as Company X. Currently no studies focused on intrapreneurship have been conducted within Company X. Innovative practices are not demonstrated as much as desired at the local manufacturing plant of company X and the levels of intrapreneurship within the manufacturing plant are currently still unknown. With the automotive industry being such an important contributor to the South African economy, it might be beneficial to do a similar study pertaining to multiple companies within the industry and value chain. This can assist in creating a bigger awareness within the industry, so that the affected organisations can have a more intrapreneurial approach towards business. The study can furthermore be adapted to consider a more technical approach of production facilities within South Africa and the intrapreneurial approach and innovations implemented to insure productivity and future investments, locally and international, within the production sector of South Africa.

- Description: Internationally, there is a growing drive towards inter-governmental assistance with tax matters, including assistance in the collection of outstanding tax debt. The purpose of this study is the consider the development of South Africa’s ability to assist with the collection of foreign tax debt. The South African common law revenue rule precludes South Africa from rendering assistance with the recovery of a foreign tax debt. The revenue rule, however, may be abrogated through legislation. Analysis of section 93 of the Income Tax Act1 and section 185 of the Tax Administration Act2 indicates that a pre-requisite for South Africa to render assistance with the collection of a tax debt is the existence of an international tax agreement between South Africa and the requesting state which makes provisions for such assistance. It was also found that the South African Revenue Service (SARS) would not be able to rely on section 172 of the Tax Administration Act in order to obtain a civil judgement for recovery of a foreign tax debt. Interpretation of these provisions in light of the Constitution3 and the Promotion of Administrative Justice Act4 (PAJA) indicates that they do not violate the Constitution, but actions taken by SARS may be subject to judicial review under the PAJA. After analysis of South Africa’s bilateral international tax agreements, it was found that 22 agreements contain provisions for assistance with collection of a tax debt. A review of the Multilateral Convention for Mutual Administrative Assistance in Tax Matters indicates that South Africa and 73 other countries are bound by it. Analysis of the provisions of the international tax agreements and the South African case law dealing with conflicts between international agreements and domestic legislation indicates that the South African courts would give preference to the provisions of the international agreement over domestic legislation in the case of a conflict. A review of selected cases involving assistance provisions in international tax agreements suggests that the South African courts will apply the assistance provisions to taxes that arose prior to the effective date of the assistance provisions.

- Description: In closed loop control systems fault isolation is extremely difficult due to the fact that if feedbacks are corrupted or actuators can’t produce a desired output, a system reacts due to an increase in error between the measured variable and the set input variable, which can cause oscillations. The goal of this project is to develop a fault detection and isolation system for the isolation of faults, which cause oscillatory conditions on a GE Diesel-Electric Locomotive’s excitation control system. The proposed system will illustrate the use of artificial neural networks as a replacement to classical analytical models. The artificial neural network model’s design will be based on model-based dedicated observer theory to isolate sensor, as well as component faults, where observer theory will be utilised to effectively select input-output data configurations for detection of sensor and component faults causing oscillations. Owing to the nature of the locomotive’s data acquisition abilities, the model-based observer design will utilise historical data to design an effective model of the system which will be used to perform offline sampled fault detection. This method is proposed as an alternative to trend checking, data mining, etc. Faults are thus detected through the use of an offline model-based dedicated observer residual generator. With the use of a neural network a number of parameters affect the accuracy of the network where the primary source of ensuring an accurate model is training. The project highlights and experiments with these parameters to ensure an accurate model is trained with the use of the gradient descent training algorithm. The parameters which are considered are learning rate, hidden layer neurons, momentum and data preparation. The project will also provide a literature review on residual evaluation techniques used in practice and describe and evaluate the proposed method to perform residual evaluation for this specific application. The proposed method for residual evaluation was based on two principles, namely the moving average, as well as the simple thresholding techniques. The developed FDI system’s performance was measured against known faults and produced 100% accuracy for the detection and isolation of sensor and components causing oscillatory conditions on the locomotive’s excitation system.

- Description: Globalization has had a profound impact on the business environment of organizations and on the lives of employees in most countries. Previously sheltered markets were suddenly opened up to intense international competition. Organizations had to improve the efficient and effective utilization of resources to retain and gain market shares. Even organizations which are still prospering today in the face of serious competition, cannot be sure of continued success in the next financial year. Astute owners and managers are acutely aware of the need to continually and consciously seek the competitive edge for their businesses. Market forces exert continuous pressure on organizations and their employees to increase performance to keep up with ever rising demands. Concurrently there are rising pressures from civil society, easily mobilized through social media, for organizational leaders to be more ethical, moral and socially responsible. Employers are currently expected to not only take care of the wellbeing of their employees, but also the wellbeing of the communities in which they operate. The challenge is clearly to find a business model that can increase individual and organizational performance, while at the same time create high levels of wellbeing for employees and thereby creating a spill-over effect to influence the wellbeing of their social environment positively. To this end, the literature was reviewed to identify constructs which could provide a solid ethical and moral managerial foundation, increase performance and create high levels of wellbeing at the same time. Servant Leadership, Workplace Trust, Work Engagement and Workplace Wellbeing were identified as constructs which could fulfill these requirements. As measurement lies at the heart of scientific endeavour, the selection of appropriate measuring instruments was considered to be equally important. The Servant Leadership Survey (Van Dierendonck and Nuijten, 2011), the Workplace Trust Survey (Ferres, 2001), the Utrecht Work Engagement Scale (Schaufeli et al, 2002) and the Work Wellbeing Questionnaire (Parker and Hyett, 2011) were selected as the most suitable instruments. These instruments are deemed to measure the constructs thoroughly through a combined total of 114 items and 18 dimensions. Three primary aims were identified for the study namely, determining the configurational portability of the instruments, investigating the relationships between the variables to determine their direct and sequential effect on wellbeing and establishing whether structural models of the findings could be built. The main findings indicate that each of the variables explain significant proportions of the variance in Work Wellbeing directly as well as indirectly through their effect on the other variables of the study. It seems that these variables contribute to fostering a psycho-organizational climate conducive to increased wellbeing.

Concurrently there are rising pressures from civil society, easily mobilized through social media, for organizational leaders to be more ethical, moral and socially responsible. Employers are currently expected to not only take care of the wellbeing of their employees, but also the wellbeing of the communities in which they operate. The challenge is clearly to find a business model that can increase individual and organizational performance, while at the same time create high levels of wellbeing for employees and thereby creating a spill-over effect to influence the wellbeing of their social environment positively. To this end, the literature was reviewed to identify constructs which could provide a solid ethical and moral managerial foundation, increase performance and create high levels of wellbeing at the same time. Servant Leadership, Workplace Trust, Work Engagement and Workplace Wellbeing were identified as constructs which could fulfill these requirements. As measurement lies at the heart of scientific endeavour, the selection of appropriate measuring instruments was considered to be equally important. The Servant Leadership Survey (Van Dierendonck and Nuijten, 2011), the Workplace Trust Survey (Ferres, 2001), the Utrecht Work Engagement Scale (Schaufeli et al, 2002) and the Work Wellbeing Questionnaire (Parker and Hyett, 2011) were selected as the most suitable instruments. These instruments are deemed to measure the constructs thoroughly through a combined total of 114 items and 18 dimensions. Three primary aims were identified for the study namely, determining the configurational portability of the instruments, investigating the relationships between the variables to determine their direct and sequential effect on wellbeing and establishing whether structural models of the findings could be built. The main findings indicate that each of the variables explain significant proportions of the variance in Work Wellbeing directly as well as indirectly through their effect on the other variables of the study. It seems that these variables contribute to fostering a psycho-organizational climate conducive to increased wellbeing.

- Description: In this thesis we consider nonholonomic Riemannian manifolds, and in particular, left- invariant nonholonomic Riemannian structures on Lie groups. These structures are closely related to mechanical systems with (positive definite) quadratic Lagrangians and nonholo- nomic constraints linear in velocities. In the first chapter, we review basic concepts of non- holonomic Riemannian geometry, including the left-invariant structures. We also examine the class of left-invariant structures with so-called Cartan-Schouten connections. The second chapter investigates the curvature of nonholonomic Riemannian manifolds and the Schouten and Wagner curvature tensors. The Schouten tensor is canonically associated to every non- holonomic Riemannian structure (in particular, we use it to define isometric invariants for structures on three-dimensional manifolds). By contrast, the Wagner tensor is not generally intrinsic, but can be used to characterise flat structures (i.e., those whose associated parallel transport is path-independent). The third chapter considers equivalence of nonholonomic Rie- mannian manifolds, particularly up to nonholonomic isometry. We also introduce the notion of a nonholonomic Riemannian submanifold, and investigate the conditions under which such a submanifold inherits its geometry from the enveloping space. The latter problem involves the concept of a geodesically invariant distribution, and we show it is also related to the curvature. In the last chapter we specialise to three-dimensional nonholonomic Riemannian manifolds. We consider the equivalence of such structures up to nonholonomic isometry and rescaling, and classify the left-invariant structures on the (three-dimensional) simply connected Lie groups. We also characterise the flat structures in three dimensions, and then classify the flat structures on the simply connected Lie groups. Lastly, we consider three typical examples of (left-invariant) nonholonomic Riemannian structures on three-dimensional Lie groups, two of which arise from problems in classical mechanics (viz., the Chaplygin problem and the Suslov problem). , Thesis (PhD) -- Faculty of Science, Mathematics (Pure and Applied), 2017

- Description: The objective of the study is to examine discourses of gender and dimensions of social difference implicated in female sex workers’ (FSWs) justifications of, and resistances to, intimate partner violence (IPV). Individual narrative interviews were conducted with FSWs (n=11) who were affiliated with the Sex Workers Education and Advocacy Taskforce (SWEAT). The participants were mostly women of colour (n=10), with a low socio-economic status, and between 31 and 51 years of age. Intersectionality and features of Foucauldian discourse analysis, as described by Parker (1992), informed the analysis of the interview data. In personal interviews, participants interrogated aspects of their own and their partners’ lives that they viewed as playing a significant role in the aetiology and experience of IPV. They drew on a discourse of violent black masculinity, developmental discourses, and patriarchal ideology to justify and resist their partners’ violent behaviour. They also positioned themselves and their ‘spoiled’ identities as playing a role in the experience of violence. Participants pointed to the construction of sex work as ‘dirty work’ and the role that this played in legitimising the violence that was directed at them by intimate partners. In relation to this positioning and its consequences in terms of justifications for violence, my analysis highlights occasions in which gender ideology is re-appropriated for the purpose of challenging the legitimacy of these interpretative frames. While gender politics is central to my analytic observations, my analysis demonstrates how intersections with race and class shape the specificities of FSWs experiences of IPV. In doing so, this study aims to broaden current insights into the phenomenon of IPV, as it does not only focus on gender discrimination, but on the complex interaction between various systems of oppression.

- Description: Monitoring and evaluation is a key contributing factor in the accomplishment of the vision, mission and strategic goals of the department. It is an on-going communication, undertaken in partnership between employees and their immediate supervisors. This research study focused on assessing the performance management system as a tool to improve performance in Ngqushwa Local Municipality. It has been found that Ngqushwa Local Municipality has undertaken measures to implement the performance management system which is aligned with legislative frameworks i.e. Republic of South African Constitution of 1996, Municipal Systems Act 32 of 2000, Municipal Structures Act 117 of 1998, Municipal Finance Management Act 56 of 2003, Public Service Regulation 2001, and Monitoring and Evaluation Frameworks. However, the research findings showed that such efforts were not sufficient in terms of implementation of Performance Management System. The study suggested that 1) the system should also accommodate employees who are in lower levels as way to strengthen the implementation of the system; 2) Involvement of stakeholders should be prioritised so as to promote ownership of the system 3) Continuous training of employees and feedback should also be considered.

- Description: This study investigates the public participation strategies in the provision of low –income housing. The purpose is to look at the effectiveness of the public participation strategies. In order to achieve this goal, it was necessary to review literature on public participation to advance the argument that public participation is an integral part of local government and the community at large. Currently, public participation permeates all legislation, impacting on local government in South Africa. It enhances individual and group esteem and enables municipal functionaries to understand crucial issues that serve as an impetus for policymaking. A supportive objective was to identify challenges that may be experienced by the Buffalo City Metropolitan Municipality with public participation in low-cost houses. The study adopted qualitative data collection instruments, which were used to collect data. The face-to-face interviews with the total sample of this study consisted of fourteen (14) participants comprising six (6) municipal officials, (3 officials from each of the Public Participation and the Integrated Development Units) and four (4) ward councillors and committee members, one (1) each from wards 1, 6, 46 and 47. For the purpose of this study, purposive (non-probability) or judgemental sampling was used. The qualitative data was analysed thematically using coding and categorising data into themes. The findings of this study revealed that there is a lack of public participation by the local communities in development projects. Also, ward committees do not have a platform to participate at the representative forums and during the IDP/budget hearings. In this regard, the study made recommendations on the participation strategies in order to tackle the challenges faced in the provision of low-income housing.

- Description: Protected areas connect socio-economic and ecological systems through their provision of ecosystem goods and services. Analysis of ecosystem services allows the expression of ecological benefits in economic terms. However, cultural services, such as recreation opportunities, have proved difficult to quantify. An important challenge for the analysis of cultural services is to understand the geography of service provision in relation to both human and ecological system elements. We used data on visitation rates and measures of context, content, connectivity, and location for 64 private land conservation areas (PLCAs) to better understand geographic influences on cultural service provision. Visitation to PLCAs was influenced by a combination of ecological and socio-economic drivers. Variance partitioning analysis showed that ecology explained the largest proportion of overall variation in visitation rates (26%), followed by location (22%). In tests using generalized linear mixed models, individual factors that significantly explained visitation rates included the number of mammal species, the number of Big 5-species (ecological variables), the number of facilities provided (infrastructure) and average accommodation charges (affordability). Our analysis has important implications for the economic sustainability of PLCAs and more generally for understanding the relevance of spatial variation for analyses of cultural services.

- Description: Property development (PD) is basically driven by the need or demand from the people. Sustainable property development has emerged in response to a global problem – and the need to maintain environmental integrity, according to Gurry (2011) cited by Botha (2013: 7). Keeping and Shiers (2004) state that property development, as a whole, has to balance social, economic and environmental needs. Emanating from the above, any successful development project must offer investors security, infrastructure and efficiency and should also put the needs of citizens at the forefront of all its planning activities. Availability of land, existing infrastructure, availability of finance, economic conditions, political influence and corruption always influence growth of property development in any area. This study aims to identify factors that contribute to lack of property development in Mthatha. Data collected shows that the challenges sometimes lead to failure and delays of the development. The purpose of this study is to identify these challenges, investigate the available literature, consider what has been done so far to address these challenges and make recommendations. It is essential to understand the state of the town and perceptions of the people in the area dealing with Property Development. Mthatha is the main focus of the study because of the perceived number of failed and delayed property development initiatives. The primary and secondary data collected provide the basis for understanding challenges that lead to such failures and delays. This research was conducted by means of a review of the related literature and an empirical study. The empirical study was conducted using a quantitative statistical approach by distributing research questionnaires to members falling within the sample population. The primary objective of the study is to develop a framework for successful implementation of property developments in Mthatha. The study’s findings reveal shortcomings which contribute to the study’s identified problems relating to property development in Mthatha, namely: decaying infrastructure, shortage of land, implementation of the IDP, availability of finance to promote real estate developments, political influence and corruption. Wikipedia defines Property Development as a “multifaceted business encompassing activities that range from the renovations and release of existing buildings to the purchase of land and the sale of improved land or parcels to others”. Harvey and Jowsey (2004), as cited by Botha (2013: 5), define Property Development as a process that involves changing or intensifying the use of land to produce buildings for occupation.
