- Description: The Keiskamma catchment has undergone significant land use/cover changes (LUCC) underpinned by land use policy reforms and climate change. However, the hydrological responses of the catchment to LUCC are not fully understood. This study sought to assess the hydrological response of the Keiskamma catchment to LUCC at catchment and hillslope scale using remote sensing, GIS, hydrological modelling and field experiments. Catchment scale assessments first involved LUCC mapping in IDRISI TerrSet software, using supervised image classification for two sets of multispectral imagery; namely Landsat Thematic Mapper (TM) of 1994 and Landsat 08 Operational Land Imager (OLI) of 2016. The LUCC maps provided an indication of LUCC over time and were prerequisite land use inputs for modelling the hydrologic response of the catchment. The Soil and Water Assessment Tool (SWAT) hydrologic model was used to model the hydrologic response of the catchment to LUCC. The Sequential Uncertainty Fitting (SUFI-2) in SWAT-CUP was used to assess model performance and uncertainty analysis. The influence of rainfall on the hydrologic response of the catchment was also assessed using linear regression. One of the prominent forms of LUCC in the Keiskamma catchment, particularly central Keiskamma is P. incana shrub encroachment. Field experiments were set up to investigate the hydrologic impacts of P. incana shrub invasion at hillslope scale, as well as to validate the results obtained by the SWAT hydrologic model. Field experiments included an assessment of the Landscape Organisation Index (LOI) of the invasion, as well as assessing of surface conditions, surface runoff (L), volumetric soil water content (cm³/cm³) and sediment loss (grams) under P. incana, grass and bare-eroded areas. High image classification accuracy assessment values of 87.2 % and 87.4 % for 1994 and 2016 respectively were obtained, with a Kappa coefficient of 0.84 for both sets of imagery. Results of the study revealed a significant increase in woody vegetation encroachment, specifically shrub invasion, forest expansion in the upper parts of the catchment, as well as an increase in exotic and invasive vegetation species within the riparian zone. The SWAT model showed a good (NSE=0.69, R²=0.69 and RSR =0.56) and unsatisfactory (NSE=0.4, R²=0.4 and RSR 0.79) model performance for calibration and validation respectively. However, for both the calibration (p-factor =0.77; r-factor 1.03) and validation (p-factor =0.92; r-factor 1.38) periods there was acceptable uncertainty as indicated by the p- and r-factor statistics. The mean annual streamflow (-71.4 %), surface runoff (-98.8 %), soil water content (-4.5 %), evapotranspiration (-5.3 %), groundwater (-79.5 %) and sediment loss (-99.9 %) decreased from 1994 to 2016. The impoundments in the catchment viz Cata, Mnyameni, Binfield, Sandile, Debe and Dimbaza dams, also contributed significantly to the streamflow reduction. A strong correlation (r= 0.61) between the declining streamflow (m3/s) and rainfall (mm) was observed. At hillslope scale, P. incana invasion was characterised by a low LOI, owing to large inter-shrub bare patches and poor soil surface conditions characterised by soil surface crusting, conducive to high runoff generation and connectivity. High surface runoff and soil losses were evident under P. incana and bare-eroded areas. Volumetric soil water content was high under grass and P. incana tussocks, intermediate in P. incana inter-patches and low in bare-eroded areas. The findings and analysis of this study conclude that the hydrologic response of the Keiskamma catchment was influenced significantly by LUCC in the form of extensive invader shrub encroachment, expansion of forestry using exotic tree species, impoundments, as well as the infestation of riparian zones by invasive vegetation. Management of woody shrub encroachment and alien invasive plants as well as indigenous forest species utilisation should be considered as amongst the key efforts towards restoring the ecohydrological integrity of the Keiskamma catchment.

- Description: While there has been substantial research on Loyalty Programmes in the last two decades, little has been done in the South African Airline Industry. This study uses the Social exchange theory, Relationship marketing theory and Commitment-trust theory to provide an understanding of the factors, which influence loyalty programmes in the South African Airline Industry. The methodology used involved a self-administrated on-line questionnaire from the sample, which comprised of 1090 respondents. From the total respondents, 172 belonged to one or more Airline Loyalty Programmes. This study focused on the latter. An email containing a Universal Resource Link (URL) to the survey was sent to the Nelson Mandela University Business School‟s Marketing Department to distribute to current first-year MBA students, who also had to circulate the survey to at least ten other people. A proposed conceptual model was compiled and tested using exploratory factor analysis. The result of the study confirmed that the measurement instrument is in order and that attitude and behaviour are strong determinants of the loyalty programme. Communication, flexibility, general assessment, rewards personal, rewards tangible, rewards monetary and trust are factors that influence the loyalty programme, which are driven by the attitude of the participant in the programme. On the other hand, communication, flexibility, general assessment, rewards personalisation, purchase behaviour and trust are factors that influence the loyalty programme, which are driven by the behaviour of the participant in the programme. This study concludes with managerial recommendations that will enable managers to identify factors which influence loyalty programmes in the South African Airline Industry. This will enable managers to make informed decisions when formulating and implementing successful programmes. Some of the recommendations call for a review and repositioning of the value proposition for the existing loyalty programmes. It is also recommended that loyalty programmes are value-based in order to convert loyalty programme customers to loyal customers. In addition, majority of the loyalty programme customers call for loyalty programmes that offer programmes that non-expiry points with personalised service offering. The organisations that offer loyalty programmes in the Airline Industry also need to design clear communication strategies that will provide a holistic and targeted approach to customer engagement.

- Description: Herein an alternative approach to the conventional batch synthesis of L-menthyl glyoxylate hydrate (MGH), an important intermediate in the synthesis of drugs of importance is reported, through flow chemistry technology. MGH was initially synthesized in batch and various reaction parameters optimized. It was found to proceed to completion after 6 hours of esterifying glyoxylic acid with excess alcohol (L-menthol) in the presence of a catalyst, ideally amberlyst-15 (an ion exchange resin) at 105 °C giving a yield of 72 %. The batch reaction conditions were adopted in a continuous flow synthesis setup, using the Labtrix Start system, in which reaction conditions were optimized. The optimization of glyoxylic acid conversion (92 %) in the Labtrix Start system gave reaction conditions that resulted in low MGH selectivity (25 %) whereas the optimization for MGH selectivity (100 %) gave a conversion a poor glyoxylic acid conversion (15 %). The FlowSyn system fitted with a column reactor gave the best results, in which the optimum conditions were an excess of L-menthol (1.5 M, 6.0 equiv.), temperature (80 °C) and a residence time of 2.5 minutes with a high selectivity (77 %) and average conversion (50 %). The optimized reaction conditions for conversion and selectivity on the different flow systems did not vary significantly and similar trends were observed for the systems. It was shown that an increase in temperature, mole equivalents and residence time led to an increase in MGH conversion in all flow systems. The scale up of the esterification reaction from the Labtrix Start system (19 μL microreactor) to the FlowSyn system fitted with a 2 mL reactor chip, showed that the reaction proceeds with a slight drop in selectivity from 100 % to 92 % while conversion dropped from 15 to 12 %. On the contrary, a significant drop in conversion and selectivity were observed when the FlowSyn column reactor was up-scaled to the Elite-tubular furnace, owing to the poor mixing in the larger channel size reactor.

- Description: Blended learning constitutes a key element of the NMMU’s Vision 2020; therefore, creating the expectation that academics from the NMMU will implement and utilise blended learning as part of their teaching pedagogy. Implementation reports drawn from Moodle (the learning management system utilised by NMMU) indicates that there are still numerous departments that are not fully utilising blended learning. The aim of this study was thus to determine the factors that impact on the acceptance and implementation of blended learning by academics at the NMMU. A modified version of the Technology Acceptance Questionnaire was electronically distributed to academics from the various NMMU campuses in order to collect the empirical data, with purposeful non-probability sampling being employed. The results indicated that factors, such as perceived usefulness, the student-centered nature of blended learning, the appeal of such environments to students, accessibility, as well as administrative- and communication benefits, had a positive influence on blended learning adoption. Lack of time and lack of knowledge with regard to blended learning use and implementation, concerns regarding accessibility, and lack of capacity and technical support were cited as issues that hampered blended learning implementation.

- Description: The estimation of variance components serves as an integral part of the evaluation of variation, and is of interest and required in a variety of applications (Hugo, 2012). Estimation of the among-group variance components is often desired for quantifying the variability and effectively understanding these measurements (Van Der Rijst, 2006). The methodology for determining Bayesian tolerance intervals for the one – way random effects model has originally been proposed by Wolfinger (1998) using both informative and non-informative prior distributions (Hugo, 2012). Wolfinger (1998) also provided relationships with frequentist methodologies. From a Bayesian point of view, it is important to investigate and compare the effect on coverage probabilities if negative variance components are either replaced by zero, or completely disregarded from the simulation process. This research presents a simulation-based approach for determining Bayesian tolerance intervals in variance component models when negative variance components are either replaced by zero, or completely disregarded from the simulation process. This approach handles different kinds of tolerance intervals in a straightforward fashion. It makes use of a computer-generated sample (Monte Carlo process) from the joint posterior distribution of the mean and variance parameters to construct a sample from other relevant posterior distributions. This research makes use of only non-informative Jeffreys‟ prior distributions and uses three Bayesian simulation methods. Comparative results of different tolerance intervals obtained using a method where negative variance components are either replaced by zero or completely disregarded from the simulation process, is investigated and discussed in this research.

- Description: The aim of this research was to examine the causes and consequences of the shortage of electrical artisans at Eskom, using the Southern Region as a case study. Eskom used to be one of the leading public enterprises in the training of artisans to fulfil its own demand as well as to meet industry demand. This research reveals that this is no longer the case. Eskom Southern Region, a sub-division of Eskom Holdings, employs about 1700 employees. More than three quarters of these employees are employed in departments that utilise mostly electrical artisans. Natural attrition and the curtailment on the number of employees indentured and trained as electrical artisans has presented the Eskom Southern Region with a skills acquisition and retention challenge. Against this background, the study sought to discover how far Eskom Southern Region implements training and development interventions and recruitment and retention strategies in response to skill shortages. The study is based on a review of literature on skill shortages, a questionnaire opinion survey on skill shortages completed by employees at Eskom Southern Region, document study, and interviews with relevant stakeholders. The empirical study confirmed the findings of the research and skills shortages were identified for particular positions employing electrical artisans. The results show worsening skill shortages and hard-to-fill vacancies. The study proposes recommendations that encompass strategic responses, workplace-based strategies, and training-based strategies to address the shortage of electrical artisans.

- Description: As the global marketplace becomes more integrated and consumer specialists develop an international focus, developing useful scales to profile consumer decision-making styles in other cultures becomes important. Comparing the decision-making styles of consumers from different countries would thus contribute to the understanding of the effect of the marketing environment as well as of the cultural factors on consumer decision-making styles. It would also be significant to determine if the decision-making styles of foreign consumers differ from those of local ones. The influx of foreign students enrolled at South African Universities and Technikons has resulted in an increase in the number of consumers who have to make purchases connected to their daily lives within a different cultural environment. An understanding of students as consumers and their decisionmaking processes is important to marketers, particularly as students are recognised as a specialised market segment for a variety of goods and services. It would thus be significant to determine if the decision-making styles of foreign students differ from those of local students. This exploratory study investigates the decision-making styles among Chinese, Motswana and South African Caucasian students in a South African context, with a view of verifying the international applicability of the Consumer Styles Inventory (CSI) developed by Sproles and Kendall (1986). Only students with a Caucasian background were included in an attempt to avoid the influence of the different subcultures amongst South African students. It was found that Sproles and Kendall’s (1986) model did not fit the South African samples. It was furthermore found that differences exist among Motswana, Chinese and Caucasian students in consumer decision-making styles. The mean value for the “Novelty-fashion conscious” style was number one in the list of factors for Chinese and Motswana students and second for the Caucasian sample. “Price conscious” style, however, was number one for the Caucasian students.

- Description: The research problem addressed in this study was to determine the challenges facing the financial manager in the manufacturing organisation and the possible ways of surmounting these challenges. To achieve this objective, relevant literature was reviewed and an empirical survey conducted. The main challenges identified are discussed under the following headings: · Regulatory requirements; · Information age; · Employees; · Economic environment; Each challenge was broken down into sub-challenges that were analysed using literature identified in the literature study. This information was used to develop a questionnaire to test the degree to which financial managers working for manufacturing organisations are challenged. The empirical results obtained indicate a strong concurrence with the literature study emphasising the importance of the identified challenges and the best possible ways of surmounting these challenges.

- Description: In this mini-dissertation, an investigation of the municipal credit control policy, with specific reference to the Nelson Mandela Metropolitan Municipality was undertaken. The dissertation comprises six chapters. The study is based on the assumption that the existing credit control policy currently (2001) used by the Nelson Mandela Metropolitan Municipality to collect service arrears has failed and that this failure is the reason why the Municipality is struggling to survive financially. This is affecting the rendering of services. The validity of this assumption was investigated. The primary objectives of the research included, inter alia, to provide a brief theoretical background on the transformation of local government in South Africa. This was followed by an investigation of the role of South African local government and the impact of non-payment for municipal services, with specific reference to the Nelson Mandela Metropolitan Municipality. The empirical survey, the research methodology and the interpretation of the research findings are described. This is followed by an explanation of the survey questionnaire used for the accumulation of data needed for the analysis. The research findings of the empirical survey were statistically analysed and reported.
